What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, such as green plants.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes like photosynthesis and respiration.

Front

What is exponential growth?

Back

Exponential growth is a pattern of growth where the quantity increases at a constant rate per time period, leading to a rapid increase over time.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria convert nitrogen gas from the atmosphere into a usable form for plants and animals through a process called nitrogen fixation.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, such as mosses and lichens in primary succession.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that shows how a population grows rapidly at first and then slows as it reaches carrying capacity.

Front

What is the role of fungi in ecosystems?

Back

Fungi decompose organic matter, recycling nutrients back into the soil, and can also form symbiotic relationships with plants.

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, starting with pioneer species.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
