1. what is mr. white’s favorite animal?

a. bull
b. spider
c. shark!
d. gerbil

Explanation:

• Question 31: Birth and death rates are influenced by environmental factors like food availability, disease, and habitat. They are not always equal, don't vary independently of each other in a completely isolated way, and are not constant over time.
• Question 32: In a food - chain, energy decreases at each level due to energy loss as heat during metabolic processes. Only about 10 - 20% of energy is transferred to the next trophic level.
• Question 33: Available resources directly determine how many individuals of a species an environment can support, which is the carrying capacity. While other factors like predators and species diversity can have an impact, available resources are the most direct determinant.
• Question 34: Carrying capacity can vary with environmental conditions such as changes in climate, availability of water and food, and habitat alteration. It is not the same for all populations and applies to all living organisms, not just animals.
• Question 35: Without any context about Mr. White, this question cannot be answered based on biological knowledge. But assuming no additional context is given, it's a random - choice question.

Answer:

1. c. They respond to environmental factors
2. c. It decreases at each level
3. b. Available resources
4. c. It can vary with environmental conditions
5. No answer can be determined from the given academic context (if only considering biological knowledge)
