What is the role of sharks in the ocean ecosystem?

Back

Sharks are apex predators that help maintain the balance of marine life by controlling the population of other species, thus supporting biodiversity.

Front

What are the consequences of overfishing on marine biodiversity?

Back

Overfishing can lead to the decline or extinction of species, disrupting food chains and reducing biodiversity in the ocean.

Front

What does biodiversity mean?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and their interactions.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy, such as herbivores like rabbits.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is the impact of introducing nonnative species to an ecosystem?

Back

Nonnative species can disrupt local ecosystems by outcompeting native species for resources, leading to declines in biodiversity.

Front

What are biotic factors in an ecosystem?

Back

Biotic factors are living components of an ecosystem, such as plants, animals, and microorganisms, that affect the environment and other organisms.

Front

What are abiotic factors in an ecosystem?

Back

Abiotic factors are non-living components of an ecosystem, such as climate, soil, water, and sunlight, that influence living organisms.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.

Front

How does climate change affect ecosystems?

Back

Climate change can alter habitats, affect species distributions, and disrupt food chains, leading to loss of biodiversity.
