Question

1. in a predator - prey relationship, which of the following scenarios would most likely occur if most predators were removed from an ecosystem? a. the prey would immediately evolve new traits b. the prey population would remain stable c. the prey population would likely increase d. the prey population would likely decrease 42. what is the process of adaptation? a. the extinction of species that cannot adapt. b. the random changes in an organisms dna c. the gradual change in species due to human intervention d. the process by which an organism becomes better suited to its environment 43. what is the primary function of the nitrogen cycle? a. to store nitrogen in the atmosphere indefinitely b. to convert nitrogen into oxygen for respiration c. to decompose organic matter into nitrogen gas d. to maintain the availability of nitrogen in ecosystems by converting nitrogen between different chemical forms

Explanation:

• For question 41: Predators control prey population. Without them, prey face less predation - pressure, so population is likely to increase.
• For question 42: Adaptation is the process by which organisms become better - suited to their environment over time.
• For question 43: The nitrogen cycle's main function is to maintain nitrogen availability in ecosystems by converting nitrogen between different chemical forms.

Answer:

1. C. The prey population would likely increase
2. D. The process by which an organism becomes better suited to its environment
3. D. To maintain the availability of nitrogen in ecosystems by converting nitrogen between different chemical forms
