Part A: Design a food chain with four trophic levels, and identify the organism in each level. What happens to energy as it travels from the bottom up? (3 points)
Part B: Can humans ever occupy the lowest, or first, trophic level? Why or why not? (1 point)

Answers

Answer:

Part A: Primary producer - plants (ex: sunflowers), Primary consumers- herbivores(ex: rabbits), Secondary consumers - omnivores and carnivores (ex: snake), tertiary consumers - omnivores and carnivores (ex: foxes), A-p-e-x predators - can be omnivores or carnivores (ex: coyote)

Energy decreases as it travels from the bottom of an energy pyramid, every time energy passes from one tropic to another, the predator only gets 10% of the total energy, or the stored energy, the rest of the energy has already been used up.

Part B: Humans cannot ever occupy the lowest or first tropic level, because the first tropic level is for producers like plants, humans are not producers and therefore cannot be at the first tropic level.

Which of the following descriptions is MOST plausible for an ancestor of bats? An animal with-
A: two limbs and webbed toes.
B: a long tail that ate insects and lived in forests.
C: four limbs and a membrane consistent with gliding.
D: four fins that glided through the water.

Answers

Answer:

C

Explanation:

Four limbs and a membrane consistent with gliding are the structures found in ancestors of bats. Therefore, option (C) is correct

What is patagium?

A membrane called the patagium helps animals glide or fly. Bats, birds, dromaeosaurs, pterosaurs, gliding mammals, flying lizards, and flying frogs have the structure. The uropatagium (particularly in bats) or interfemoral membrane connects an animal's hind limbs.

Bats' wing skin extends from the abdomen to the tip of each digit, connecting the forelimb to the body. Bat patagiums have four parts:

Propatagium: neck-to-first-digit patagium.Dactylopatagium: digits.Plagiopatagium: between final digit and hindlimbs.Uropatagium: posterior flap between hindlimbs.

Therefore, option (C) is correct.

WILL GIVE BRAINLIST!!!!! what are 3 ways that animals and plants can erode rocks in different locations?

Answers

Answer:

Hope this Helped :)

Explanation:

1.Biological weathering-Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.

2.Plants change Earth’s surface through weathering and erosion.They take minerals from  the rock. This is a type of weathering, and it weakens the rock. Eventually the  surface of the rock starts to break down and become soil.

3.As larger plants like trees start to grow in a rocky area, their roots

grow into the small cracks in the rock. Slowly, as the tree grows, its roots break the rock apart. This forms more soil and makes it easier for other plants to grow there as well.

4.When too many animals live in one place,  they tend to eat and trample all the plants. Without the plants to protect the soil, it is  more likely to be eroded by wind and water.
