Brief Biology Review

Biotic

Referring to living organisms and their interactions within ecosystems, biotic factors include plants, animals, fungi, and microorganisms.

Abiotic

Referring to non-living components of an ecosystem, such as temperature, water, and minerals. Abiotic factors influence the living organisms within a habitat.

Producer

Organisms (usually plants and algae) that produce their own food through photosynthesis or chemosynthesis, serving as a primary food source for other organisms in an ecosystem.

Consumer

Organisms that obtain their energy by feeding on other organisms, including herbivores, carnivores, and omnivores. They play a crucial role in food chains and energy transfer within ecosystems.

Decomposer

Organisms that break down dead or decaying organic matter, returning nutrients to the ecosystem. They play a vital role in recycling nutrients and maintaining soil health.

Ecosystem

A community of living organisms interacting with their physical environment, including both biotic and abiotic components, which function as a unit.

Biodiversity

The variety of different species of plants, animals, and microorganisms in a particular habitat or on Earth as a whole. Biodiversity is essential for ecosystem stability and resilience.
