π Topic Summary
Ecosystems are made up of two main types of factors: biotic and abiotic. Biotic factors are all the living things in an ecosystem, like plants, animals, fungi, and bacteria. They interact with each other in various ways, such as through food chains and competition. Abiotic factors are the non-living things in an ecosystem, like sunlight, water, temperature, soil, and air. These factors play a crucial role in determining which organisms can survive in a particular environment and how well they can thrive.
