The surroundings where organisms live and interact.

A community of living organisms and their physical environment interacting together.

Living organisms within an ecosystem, like plants and animals.

Non-living physical factors in an ecosystem, such as temperature and soil.

Ecosystems that occur naturally without human intervention, like forests and ponds.

Ecosystems created or significantly altered by humans, such as gardens and crop fields.

The ways in which living organisms and their environment affect each other.

Elements needed for a successful aquarium, like fish, water, and oxygen.

The equilibrium between biotic and abiotic components ensuring life sustainability.

Problems affecting the environment on a worldwide scale, discussed at summits.

An ecosystem consists of biotic (living) and abiotic (non-living) components that interact.

Biotic interactions are how living organisms like plants and animals interact within an ecosystem.

Abiotic factors include physical elements like temperature, soil, and water that affect living organisms.

Ecosystems can be natural (like forests) or human-made (like gardens).

A garden is an ecosystem comprising various plants, animals, and abiotic components interacting.

Natural ecosystems include forests, ponds, and lakes that exist without human intervention.

Human-made ecosystems include gardens and crop fields where humans actively manage the environment.

An aquarium needs proper space, water, oxygen, and food for fish to thrive.

Abiotic components influence the growth and activities of living organisms in an ecosystem.

Abiotic components can include sunlight, temperature, soil type, and water availability.
