Are all animals that share a food source classified in the same trophic level

ANSWER QUICK PLEASE!!!

Answers

Answer:

it depends on the food web that the animal is on but they can sometimes

Explanation:

Answer:

An organism may not always occupy the same trophic level, depending on the food web. Assigning organisms to trophic levels isn't always clear-cut. For instance, humans are omnivores, meaning they can eat both plants and animals. So they may be considered both primary and secondary (or even higher!)

How does weathering help to create soil?

Answers

Weathering breaks down and loosens the surface minerals of rock. Hence, the broken rocks are transported to another place where it decomposes and forms soil. Therefore weathering is important for soil formation

Answer:

weathering breaks parent material into smaller pieces

Explanation:

I took the test and it was correct.

Living things obtain matter from their environment and release waste back into it. This matter moves in a cycle. Plants use air, water, nutrients, and sunlight to make food and grow. Some animals eat the plants and use their matter to grow. When those animals die, decomposers will grow using the matter from the animals' bodies. The decomposers release this digested matter back into the air and soil. The matter in an ecosystem is recycled. Gases are a type of matter that moves through an ecosystem. For example, oxygen and carbon dioxide are cycled between organisms and the air. The producer in the diagram takes carbon dioxide from the air. It uses this gas and water to make sugar, releasing oxygen as waste. Then the consumer breathes in the oxygen and uses it in its body. It also eats the producer for food, represented as carbon in the diagram. The decomposer takes oxygen from the air and food from the consumer or producer. The consumer and decomposer make carbon dioxide, putting it into the air. When producers use it again, the matter is recycled. Describe in words how carbon and oxygen move through an ecosystem. (my little bro needs help and I am to lazy to do it)

Answers

Answer:

"living things obtain matter from their environment and release waste back".  plants use carbon dioxide, then let out oxygen for us to use. When animals die, decomposers release the digested matter back into the air and soil. Different types of gases move throughout a ecosystem and is recycled between organisms and air. (again going back to the air recycled between a plant and a human).

Answer:

the decomposers release carbon dioxide  that help plans grow then they can do photosynthesis then the oxygen is given to animals then they die then decompose and that's a cycle

a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.

Answers

Answer:

There is no model in this question but the question can be answered based on the provided information and general knowledge of photosynthesis. The answer is:

d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.

Explanation:

Photosynthesis, which is being described in this question, is the process by which autotrophic organisms synthesize their food in the presence of sunlight. The photosynthetic process occurs in the CHLOROPLAST. However, photosynthesis occurs in two stages namely: light dependent and light independent reaction.

Light dependent reaction occurs specifically in the THYLAKOID of the chloroplast where the photons of light is absorbed by chlorophyll molecule (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.

These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis by providing the energy source for converting ADP to ATP, and NADP+ to NADPH.

A. dorsal fins appearing, disappearing, and reappearing in species of ancient aquatic reptiles, mammals, and fish
B. a species of flower changing in shape, followed by a change in the beak shape in its preferred species of pollinator
C. the shell shape of a species of snail remaining unchanged for millennia until it changes to an entirely different shape
D, whale species gradually changing from land-dwelling mammals that walked on four legs to marine mammals without legs

Answers

D

Punctuated equilibrium is a series of small, gradual changes over long periods of time.

Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).

What is Punctuated equilibrium?

Punctuated equilibrium is defined as the theory that proposes that once a species appears in the fossil record, the population will be stable, showing little evolutionary change for most of its geological history, with little or no morphological change. The condition is called statis.

This balance is the idea that evolution is rapid rather than following the slow, but steady path Darwin suggested. Long periods of stagnation with little activity are interrupted by intermittent bursts of activity in the case of extinction or emergence of new species.

Thus, Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).

In recent scientific history, the classification of the protist kingdom has changed several times. They are now grouped to consider their development over time instead of simply by what they look like or how they move. Which statement best describes the reason for these classification changes?

A. Traditional scientists did not have enough information about protists to attempt to clasify them.
B. Originally, scientists drew inaccurate conclusions about the classification of protists based on flawed data.
C. Changes in classification of this kingdom are made each time modern scientists discover a new species of protists.
D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.

Answers

Answer:

D

Explanation:

The statement that best describes the reason for these classification changes is the classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms. The correct option is D.

What are the characters of the protist kingdom?

All eukaryotes that are not fungi, animals, or plants are collectively referred to as protozoa. It is a tremendously diverse group of species as a result.

Beyond a rather straightforward organizational structure, the eukaryotes that make up this kingdom, Kingdom Protista, do not share many characteristics.

Therefore, the correct option is D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.

im pretty sure it would be c

If purple-flowered  plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first  generation of offspring should have 100% purple flowers.

Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.

In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.

oxygen aids in glucose production through respiration and supports the organism since glucose is the food for plants

The role of oxygen in photosynthesis and in cellular respiration - B Oxygen is released in photosynthesis and used in cellular respiration to produce energy.

Role of oxygen

1. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.

               6CO₂ + 6H₂O+ energy → C₆H₁₂O₆ + 6O₂

2. In respiration, the product of photosynthesis, glucose and oxygen are converted into carbon dioxide, water, and energy and oxygen is used to break down glucose

                C₆H₁₂O₆ + 6O₂ →   6CO₂ + 6H₂O+ energy
