What is the cardiovascular system?

Back

The cardiovascular system is the system in the human body that includes the heart, blood, arteries, and veins. It is responsible for transporting blood and nutrients throughout the body.

Front

Which two systems are primarily responsible for gas exchange in the body?

Back

The respiratory and circulatory systems are primarily responsible for gas exchange. The respiratory system takes in oxygen, while the circulatory system transports it to cells.

Front

What happens to the ecosystem if the population of a top predator, like eagles, decreases?

Back

If the population of a top predator decreases, it can lead to an overpopulation of their prey, such as snakes, which can disrupt the balance of the ecosystem.

Front

How does habitat destruction, like building houses, affect local wildlife such as woodpeckers?

Back

Habitat destruction can lead to a decrease in available food for local wildlife, such as woodpeckers, which can negatively impact their population.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, are essential in an ecosystem because they create energy through photosynthesis, supporting a large number of organisms.

Front

Define the term 'ecosystem'.

Back

An ecosystem is a community of living organisms interacting with their environment, including both biotic (living) and abiotic (non-living) components.

Front

What is the function of the heart in the cardiovascular system?

Back

The heart pumps blood throughout the body, supplying oxygen and nutrients to tissues and removing waste products.

Front

What are herbivores?

Back

Herbivores are animals that primarily eat plants. They play a crucial role in the food chain by transferring energy from producers to higher trophic levels.

Front

What is the significance of gas exchange in living organisms?

Back

Gas exchange is vital for respiration, allowing organisms to take in oxygen for energy production and expel carbon dioxide as a waste product.

Front

What can happen to plant life if herbivore populations increase significantly?

Back

If herbivore populations increase significantly, they may overconsume plants, leading to a decrease in plant diversity and health in the ecosystem.
