Concepts of Ecology

Front

A fundamental concept of ecology is that living organisms interact with other living organisms and interact with the physical environment.

Back

This concept highlights the interconnectedness of organisms and their surroundings, forming ecosystems where biotic and abiotic factors influence each other.

The diagram represents a food web in an ecosystem, showing the relationships between organisms such as hawks, owls, snakes, frogs, grasshoppers, mice, rabbits, caterpillars, wheat, clover, and dandelions.

Back

A food web illustrates the flow of energy and nutrients through an ecosystem, showing how organisms are interconnected as predators, prey, and producers.

Front

If the population of hawks increases, their prey populations might decrease. Later, with fewer prey, the hawk population might decrease, and the prey populations might then increase.

Back

This is an example of how ecosystems maintain stability over time, demonstrating the dynamic balance within ecosystems.

Front

A stable ecosystem is characterized by having a continual input of energy.

Back

Energy, often from the sun, is essential for maintaining the balance and functioning of ecosystems.

Front

All of Earth's water, land, and atmosphere within which life exists is known as the biosphere.

Back

The biosphere encompasses all ecosystems and living organisms on Earth, interacting with the physical environment.

Front

The study of the interactions between organisms and their interrelationships with the physical environment is known as ecology.

Back

Ecology is the study of interactions between organisms and their environment.

Front

The science of ecology is best defined as the study of the interactions of living organisms and their environment.

Back

Ecology focuses on how living organisms interact with each other and their surroundings.

Front

A self-sustaining ecosystem in a glass tank must include producers, decomposers, light, and water.

Back

Producers, decomposers, light, and water are essential for a self-sustaining ecosystem.

Front

Maintaining stability in an ecosystem most likely depends on a high level of diversity and multiple ecological niches.

Back

Ecosystem stability is supported by high biodiversity and varied ecological roles.

Front

Sharks are often followed by smaller fish that eat scraps from the organisms eaten by the shark. These smaller fish act as scavengers.

Back

Scavengers consume leftover food or scraps from other organisms.
