Question 1

What is an ecosystem?

Accepted Answer

An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with their physical environment (including air, water, and soil) within a defined area.

Question 2

What is the role of decomposers in an ecosystem?

Accepted Answer

Decomposers play a vital role in ecosystems by breaking down organic matter, such as dead plants and animals, into simpler substances. They recycle nutrients back into the environment, making them available for other organisms.

Question 3

What is photosynthesis, and why is it important?

Accepted Answer

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a form of sugar) and oxygen. It is crucial as it produces oxygen and is the primary source of energy for most living organisms.

Question 4

How does the water cycle work in an ecosystem?

Accepted Answer

The water cycle in an ecosystem involves the continuous movement of water between the atmosphere, land, and bodies of water. It includes processes such as evaporation, condensation, precipitation, and runoff.

Question 5

What is the significance of biodiversity in ecosystems?

Accepted Answer

Biodiversity is essential for the functioning and resilience of ecosystems. It provides various ecosystem services, such as pollination, nutrient cycling, and pest control. High biodiversity also increases an ecosystem's ability to adapt to environmental changes.
