Biotic

Abiotic

All non-living things in an ecosystem.

Ecosystem

A complex self-regulating system where biotic and abiotic factors interact.

Sustainability of the environment

The ability of the population of living organisms to interact and reproduce indefinitely to preserve biodiversity.

Biodiversity

The number of different types of organisms in an area, indicating a healthy and suitable environment.

Habitat

The specific place where organisms live.

Niche

The role or job an organism plays in its ecosystem.

Open Ecosystem

An ecosystem where organisms can freely enter and leave.

Closed Ecosystem

An ecosystem where organisms cannot freely enter or leave.

Biosphere

The region of the Earth where all life exists.

Atmosphere

The layer of gases that surround the Earth.

Lithosphere

The Earth's soil and outer layer.

Hydrosphere

All water on Earth.

Biome

A large geographical area that contains similar ecosystems.

Producers

Organisms that produce their own food through photosynthesis.

Consumers

Organisms that do not produce their own food but eat plants and animals to survive.

Decomposers

Organisms that chemically break down organic matter into nutrients.

Ecological Pyramid

A representation of the relationship between trophic levels in an ecosystem.

Pyramid of Numbers

Shows the number of organisms at each trophic level in a food chain.

Pyramid of Biomass

Takes into account the mass of each organism in a food chain.

Pyramid of Energy

Takes into account the energy transferred in a food chain, the most accurate type of ecological pyramid.
