Front

What is the primary source of energy for all food chains?

Back

The sun.

Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads widely in a new habitat and can outcompete native species for resources.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

How can human actions lead to the introduction of invasive species?

Back

Human actions, such as pet owners dumping unwanted pets into the wild, can lead to the introduction of invasive species.

Front

What happens to the population of smaller fish if a predator is introduced that eats larger fish?

Back

The population of smaller fish will likely increase due to reduced competition and predation.

Front

What role does the sun play in ecosystems?

Back

The sun provides the energy necessary for photosynthesis, which is the foundation of food chains.

Front

What are some effects of invasive species on native ecosystems?

Back

Invasive species can outcompete native species for food and habitat, disrupt food webs, and lead to declines in native populations.

Front

What is the significance of adaptation in natural selection?

Back

Adaptation is crucial in natural selection as it allows species to survive and reproduce in their specific environments.

Front

Can invasive species have economic impacts?

Back

Yes, invasive species can have significant economic impacts by affecting agriculture, fisheries, and tourism.

Front

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

Back

Predators control the population of prey species, which helps maintain balance in the ecosystem.
