Final answer:
In a forest community, the parts include animals such as snakes, beavers, and deer. Whales and plankton, on the other hand, are not part of a forest community but belong to marine ecosystems.
Step-by-step explanation:
The parts of a forest community include various organisms like animals and plants that interact with each other and with their environment. In the choices provided:
- Snakes: These are reptiles that live on land and could be part of a forest community.
- Beavers: These are semi-aquatic mammals known for building dams in rivers and streams within forests, so they too are part of a forest community.
- Deer: Deer are commonly found in forests and are definitely part of forest communities.
- Whales: Whales are marine mammals and do not live in forests; they belong to marine ecosystems like the intertidal zone, neritic, oceanic, and abyssal zones.
- Plankton: Plankton are tiny organisms that live in water, usually in oceans or lakes, and are not typically part of a forest community.
Therefore, the correct answers to the question 'Which of the following are parts of a forest community?' are a. snakes, b. beavers, and c. deer.
