Which term refers to the living components of an ecosystem?

• Abiotic factors

• Biotic factors

• Energy flow

• Conservation

Answer explanation

The term 'biotic factors' refers to the living components of an ecosystem, including plants, animals, and microorganisms. In contrast, 'abiotic factors' are non-living elements like water and soil.

What term is used to describe non-living components in an ecosystem?

• Biodiversity

• Interdependence

• Abiotic factors

• Human impacts

Answer explanation

The term 'abiotic factors' refers to the non-living components of an ecosystem, such as water, sunlight, and minerals, which are essential for the survival of living organisms.

Which term describes the variety of life in a particular habitat or ecosystem?

• Sustainability

• Biodiversity

• Energy flow

• Cycling of matter

Answer explanation

The term 'biodiversity' refers to the variety of life forms in a specific habitat or ecosystem, encompassing the different species, genetic variations, and ecological roles. It is crucial for ecosystem health and resilience.

What is the term for the reliance of organisms on one another for survival?

• Interdependence

• Conservation

• Environment

• Human impacts

Answer explanation

The term 'interdependence' refers to the reliance of organisms on one another for survival, highlighting the interconnectedness of species within ecosystems.

Which term refers to the management of natural resources to prevent exploitation, destruction, or neglect?

• Energy flow

• Conservation

• Cycling of matter

• Biotic factors

Answer explanation

The term 'Conservation' refers to the management of natural resources to prevent their exploitation, destruction, or neglect, making it the correct choice in this context.

What term describes the movement of energy through a food chain?

• Energy flow

• Sustainability

• Abiotic factors

• Interdependence

Answer explanation

The term 'energy flow' describes how energy moves through a food chain, from producers to consumers. It highlights the transfer of energy as organisms consume one another, making it the correct choice.

Which term refers to the process by which matter is recycled in the environment?
