What is predation?

Back

Predation is a biological interaction where one organism (the predator) kills and eats another organism (the prey).

Front

What is the first trophic level in an ecosystem?

Back

The first trophic level consists of producers, primarily plants, that convert sunlight into energy through photosynthesis.

Front

How can a change in predator or prey populations affect an ecosystem?

Back

Changes in predator or prey populations can disrupt the balance of the food web, leading to overpopulation or extinction of species.

Front

What factors are included in an ecosystem?

Back

An ecosystem includes both biotic (living) factors, such as plants and animals, and abiotic (non-living) factors, such as water, soil, and climate.

Front

What is mutualism?

Back

Mutualism is a long-term relationship between two species where both benefit from the interaction.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism (the parasite) benefits at the expense of another organism (the host).

Front

What is competition in ecology?

Back

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

Front

Define abiotic factors in an ecosystem.

Back

Abiotic factors are the non-living components of an ecosystem, including sunlight, temperature, water, and minerals.

Front

Define biotic factors in an ecosystem.

Back

Biotic factors are the living components of an ecosystem, including plants, animals, fungi, and microorganisms.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.
