Explanation:

• Question 6: When a population has unlimited resources, it grows exponentially. Logistic growth occurs when resources are limited. Carrying capacity is the maximum number of individuals an environment can support (not relevant here as resources are unlimited). Dying out is incorrect as resources are abundant.
• Question 7: Type I survivorship pattern has a low death rate, and many individuals live to old age, which is characteristic of humans. Type II has a moderate death rate at all ages. Type III has a high death rate among the young. There is no Type IV in standard survivorship patterns.
• Question 8: Secondary succession occurs in an area that has been disturbed (like by a forest fire) but where soil and some organisms still exist. Primary succession is on a newly formed area with no soil. Pioneer succession is not a standard term for this context. Symbiotic succession is not relevant.
• Question 9: A niche includes an organism's habitat, behavior, food, predators, and its impact on the ecosystem. Habitat is just the place where it lives. Ecosystem is a broader community of organisms and their environment. Species is a group of similar organisms.
• Question 10: Interspecific competition is competition between different species (sharks, dolphins, seabirds are different species) for the same resource (fish). Intraspecific competition is within the same species. Succession (primary/secondary) is about ecological change over time, not competition.

Answer:

1. a. Grow exponentially
2. a. Type I
3. b. Secondary succession
4. a. Niche
5. d. Interspecific competition
