What is a forest ecosystem?

Back

A forest ecosystem is a community of living organisms, including plants, animals, and microorganisms, interacting with their physical environment in a forested area.

Front

What is 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 a density-independent factor?

Back

A density-independent factor is an environmental factor that affects population size regardless of the population's density, such as natural disasters.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, primarily converting carbon dioxide and water into glucose and oxygen.

Front

What role does carbon dioxide play in photosynthesis?

Back

Carbon dioxide is incorporated into glucose, the main product of photosynthesis.

Front

What is a population in ecological terms?

Back

A population is defined as a group of individuals of the same species living in a specific area.

Front

What is the relationship between predators and prey in an ecosystem?

Back

Predators are organisms that hunt and consume other organisms (prey), and their populations can influence the population dynamics of prey species.

Front

What is the impact of human activities on predator populations?

Back

Human activities, such as habitat destruction and hunting, can lead to declines in predator populations, which can subsequently affect the entire ecosystem.

Front

What is the significance of disease spread in a population nearing carrying capacity?

Back

As a population nears its carrying capacity, limited resources can lead to increased competition and stress, which may result in a higher spread of diseases.

Front

What is ecological competition?

Back

Ecological competition occurs when two or more species or individuals compete for the same resources, such as food, space, or mates.
