Ecology Introduction Biotic and Abiotic Factors

Front

What are biotic factors?

Back

Biotic factors are all living things in an ecosystem, including plants, animals, fungi, and microorganisms.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living parts of the environment, such as temperature, light, water, air, and soil.

Front

What is ecology?

Back

Ecology is the scientific study of interactions among organisms, populations, and communities and their interactions with the environment.

Front

Give examples of biotic factors.

Back

Examples of biotic factors include plants, animals, bacteria, and fungi.

Front

Give examples of abiotic factors.

Back

Examples of abiotic factors include sunlight, temperature, water, soil, and air.

Front

How do biotic and abiotic factors interact in an ecosystem?

Back

Biotic factors depend on abiotic factors for survival; for example, plants (biotic) need sunlight and water (abiotic) to grow.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
