Question

List 3 biotic factors and their roles in the ecosystem.

Answer 1

Biotic factors in an ecosystem include plants, animals, and bacteria. Plants are primary producers, animals have various roles, and bacteria are decomposers.

Step-by-step explanation:

Biotic factors are the living aspects of the environment. They consist of other organisms, including members of the same and different species. Three examples of biotic factors in an ecosystem and their roles are:

1. Plants: Plants are primary producers that convert sunlight, water, and carbon dioxide into energy through photosynthesis. They are the base of the food chain and provide food and habitat for other organisms.
2. Animals: Animals play various roles in the ecosystem. Herbivores consume plants, carnivores consume other animals, and decomposers break down dead organisms and waste, returning nutrients to the ecosystem.
3. Bacteria: Bacteria are decomposers that recycle nutrients by breaking down organic matter. They play a vital role in nutrient cycling and help maintain the balance of an ecosystem.
