Question

together, all of the chemical processes that build up and break down materials in organisms are called
respiration.
metabolism.
homeostasis.
photosynthesis.

when a rabbit runs away from a fox, its muscles need
heat.
energy.
carbon.
homeostasis.

Explanation:

First Question:

• Respiration is a part of metabolism, focusing on energy release.
• Metabolism includes all chemical processes (anabolism - building up, catabolism - breaking down) in organisms.
• Homeostasis is about maintaining internal balance.
• Photosynthesis is specific to plants making food. So the correct term for all chemical build - up and break - down processes is metabolism.

• Muscles require energy to contract and enable movement. Heat is a by - product of energy use, carbon is an element in molecules, and homeostasis is about internal balance, not directly related to muscle movement for running. So muscles need energy.

Answer:

B. metabolism.
