What cycle is shown in the diagram?

Back

The Water Cycle is the process by which water circulates between the earth's oceans, atmosphere, and land, involving processes such as evaporation, condensation, and precipitation.

Non-living things that are a part of a biome are called...

Back

What is the maximum number of trophic levels a food chain can reach?

Back

A food chain can typically reach a maximum of 5 trophic levels, which include producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers.

Front

A relationship between two organisms in which one organism benefits and the other is unharmed is called...

Back

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Front

If the number of births is greater than the number of deaths in a population, what will happen to the growth of the population?

Back

The population will increase, as more individuals are being added than are being removed.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

Define the term 'biome'.

Back

A biome is a large geographical biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are the living components of an ecosystem (like plants and animals), while abiotic factors are the non-living components (like water, sunlight, and temperature).

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow.

Front

Explain the concept of carrying capacity.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support without degrading the habitat.
