Ecosystems EOC 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 role do plants play in the carbon cycle?

Back

Plants remove carbon dioxide (CO2) from the atmosphere during photosynthesis, helping to regulate atmospheric CO2 levels.

Front

Define mutualism in ecological terms.

Back

Mutualism is a type of symbiotic relationship between two species where both benefit from the interaction, such as bees pollinating flowers while feeding on nectar.

Front

What is competition in an ecosystem?

Back

Competition occurs when two or more organisms or species compete for the same resources, such as food, water, or space, which can limit their growth and survival.

Front

Explain the term 'carrying capacity'.

Back

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

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What is the impact of deforestation on biodiversity?

Back

Deforestation can lead to a decrease in biodiversity as it destroys habitats, leading to the loss of species that depend on those environments.

Front

Describe the process of decomposition.

Back

Decomposition is the process by which organic matter is broken down by bacteria, fungi, and other organisms, returning nutrients to the soil.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, productivity, and stability, allowing ecosystems to adapt to changes and disturbances.

Front

Define parasitism in ecological relationships.

Back

Parasitism is a relationship where one organism (the parasite) benefits at the expense of another organism (the host), often harming the host in the process.
