Question

read the passage. then answer the question below.

rain forests in indonesia have at least 15,000 species of plants, more than any other forest in the world. these plants include sugar palms, bornean ironwood, and durian trees.

bornean orangutans spend most of their lives in trees. staying in the trees helps the orangutans avoid predators such as the saltwater crocodiles that live in the rivers below. but other predators, such as sunda clouded leopards, can climb trees to hunt orangutans.

in a rain forest in indonesia, the bornean orangutans, the saltwater crocodiles, and the rivers make up which of the following? select all that apply.

a population
part of a community
part of an ecosystem

Explanation:

1. Population: A population is a group of individuals of the same species in a given area. But here we have multiple species (orangutans, crocodiles) and a non - living component (rivers), so it's not a population. However, if we consider each species separately, the orangutans are a population and the crocodiles are a population. But the combination of orangutans, crocodiles, and rivers is not a single population. But maybe the question considers each species as a population, so the orangutans and crocodiles can be considered as populations.
2. Community: A community is all the different populations (species) that live and interact in an area. The orangutans and crocodiles are different species, so they are part of a community (along with other species in the rainforest).
3. Ecosystem: An ecosystem includes all the living (biotic) components (like orangutans, crocodiles, plants) and non - living (abiotic) components (like rivers, soil, climate) in an area. Since we have biotic components (orangutans, crocodiles) and an abiotic component (rivers), they are part of an ecosystem.

So the correct options are:

• part of a community (because there are multiple species interacting)
• part of an ecosystem (because it includes biotic and abiotic components)
• For the "a population" option, if we consider each species: the Bornean orangutans are a population and the saltwater crocodiles are a population. But the combination of orangutans, crocodiles, and rivers is not a single population. However, if the question is considering that each species is a population, then it can be selected. But more accurately, the community and ecosystem options are more appropriate for the combination. But based on the question's options, the correct selections are part of a community, part of an ecosystem, and if we consider each species as a population, then "a population" can also be correct (for example, the orangutans are a population and the crocodiles are a population).

Answer:

• part of a community
• part of an ecosystem
• (If considering each species as a population: a population for Bornean orangutans and a population for saltwater crocodiles, but the combination of all three is not a single population. However, based on the options given, the correct selected options as per ecological definitions for the combination are)

part of a community, part of an ecosystem
