Answer:
The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
How energy flows through an ecosystem is summarized below.
Energy flows through an ecosystem in the following order:
Sun ----> Producer ---> Primary consumer ---> Secondary consumer ---> Tertiary consumer ---> Decomposer.
Some of the energy from the sun is fixed by the producer through a process known as photosynthesis. The producers are usually green plants and photosynthetic bacteria.Primary consumers feed directly on the producers.Secondary consumers feed on the primary consumers.Tertiary consumers feed on the secondary consumers.The decomposers feed on the remains of the tertiary consumers.As the energy flows from producer to the different consumers, and to the decomposer, only about 10% of the energy available in each trophic level move to the next with the rest being lost to heat.
Hence, an energy pyramid is created as we move from the lower trophic level to higher trophic levels.

what is the difference between light dependent and light indepenedent reactions
Answer:
The difference between light dependent and light independent reactions is light independent is energy from sunlight that is absorbed by Chlorophyll. Also light dependent is energy that is converted into stored chemical energy. In the independent reactions, the chemical energy basically harvests during the light dependent reactions, which drives the assembly of these sugar molecules from carbon dioxide.
How is the rate of photosynthesis affected by wavelength?
does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
A scientist is performing an experiment to determine the melting point of a new substance. Which action could increase the likelihood of obtaining accurate results?
Which of the following best describes the cytoplasm in the cell?
a watery substance where cell processes take place
a hard substance that digests food molecules
a watery substance that keeps molecules from leaving the cell
a hard substance that keeps the cell rigid
Answer: A watery substance where cell processes take place.
Explanation: Process of elimination. The 2nd and last answer choices are both immediately wrong because cytoplasm is not a hard/solid substance. And the third answer choice is wrong because the cell membrane’s job is to prevent organelles from leaving the cell, not the cytoplasm. Therefore the answer is A, a watery substance where cell processes take place.
It is a jelly-like liquid that surrounds everything inside the cell.

How are the various types of plants and fungi different from each other? What characteristics do plants and
fungi share?
Answer:
While both are eukaryotic and don't move, plants are autotrophic - making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic - taking in food for energy - and have cell walls made of chitin.

In the Osmosis Gizmo, the cell is placed in a very small chamber. Suppose a cell is placed in a large container of water with a very low solute concentration. What do you think would happen
Answer:
If a cell is placed in a large container of water with a very low solute concentration the solution will be hypotonic in nature. The water will enter inside the cell through semi-permeable membrane of cell. The cell will swell.
How does the genetic code show a shared history among all organisms?
Answer:
All living organisms store genetic information using the same molecules — DNA and RNA. Written in the genetic code of these molecules is compelling evidence of the shared ancestry of all living things. ... Some mammalian genes have also been adopted by viruses and later passed onto other mammalian hosts.

how does a trait go from a gene to a protein?
Answer:
A gene codes for a particular protein that is involved in the expression of a trait. Characteristics determined by single genes are called Mendelian traits.
Explanation:
Answer:
The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.

What would be the end result if an
experiment supports a hypothesis and
has been repeated?
A. developing a theory
B. redoing the hypothesis
C. graphing the data a different way
D. setting up another experiment based on the same
hypothesis
Answer:
A
Explanation:
The end result of repeated experiments supporting a hypothesis is for the hypothesis to become a theory.
In science, a hypothesis is a general statement that needs to be validated or invalidated by experiments. Once a hypothesis is found to be valid by several independent but similar experiments, such a hypothesis becomes a theory.
Formulation and testing of hypotheses (via experiments) represent two of the key steps in the scientific method.
The correct option is A.
