Ecology Practice Questions

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It is essential for the survival of most living organisms.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic material, recycling nutrients back into the ecosystem.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance, leading to a more stable community.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren or disturbed area, such as mosses and lichens, which help to create conditions for other species to thrive.

Front

What is a food web?

Back

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

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and phytoplankton, are organisms that produce their own food through photosynthesis and serve as the base of the food web.

Front

What is a predator?

Back

A predator is an organism that hunts and consumes other organisms (prey) for food, playing a crucial role in maintaining the balance of ecosystems.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new environment, can cause harm to native species, ecosystems, and human activities.
