What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their environment, including both biotic (living) and abiotic (non-living) components.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow from producers to consumers and decomposers.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, create their own food through photosynthesis and form the base of the food chain.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a more complex network of interconnected food chains.

Front

What causes tides in oceans?

Back

Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

Front

What is the motion of tectonic plates?

Back

The motion of tectonic plates refers to the movement of the Earth's lithosphere, which can cause earthquakes, volcanic activity, and the formation of mountains.

Front

What is a high tide?

Back

A high tide is the point at which the ocean reaches its highest level due to the gravitational pull of the moon and sun.

Front

What is the significance of a diversion of a stream in an ecosystem?

Back

Diverting a stream can create new habitats for organisms, such as frogs, by providing necessary water sources.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and pushes older crust away.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the soil.
