What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem, with producers at the base and top predators at the apex.

Front

What organisms are typically found at the base of the energy pyramid?

Back

Plants, also known as producers, are typically found at the base of the energy pyramid as they convert sunlight into energy through photosynthesis.

Front

How do animals obtain nitrogen?

Back

Animals obtain nitrogen primarily by consuming plants or other animals that contain nitrogen compounds.

Front

What is combustion and its effect on the environment?

Back

Combustion is the process of burning fossil fuels, which releases carbon dioxide and other pollutants into the atmosphere, contributing to climate change.

Front

Define commensalism in ecology.

Back

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

Front

What is competition in ecological terms?

Back

Competition occurs when two or more organisms vie for the same resources, such as food, space, or mates.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.

Front

Explain the process of photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the significance of the nitrogen cycle?

Back

The nitrogen cycle is crucial for converting nitrogen from the atmosphere into forms usable by living organisms, thus supporting life.

Front

What is the difference between mutualism and parasitism?

Back

Mutualism is a relationship where both organisms benefit, while parasitism is a relationship where one organism benefits at the expense of the other.
