Question

1. how do populations differ from communities?

communities can only include plants, not animals.
populations include habitats; communities do not.
populations are smaller than communities always.
populations consist of one species; communities consist of multiple types of species.

Explanation:

• Option 1: Communities include both plants and animals. So this option is incorrect.
• Option 2: Both populations and communities are about groups of organisms, not habitats. So this option is incorrect.
• Option 3: While populations can be smaller, it's not an absolute "always" based on the fundamental definitions. The key difference is in species composition.
• Option 4: By definition, a population is a group of individuals of the same species in a given area. A community is an assemblage of different populations (multiple species) in an area. This is the correct distinction.

Answer:

Populations consist of one species; communities consist of multiple types of species.
