Questions & Answers

Q: Why are organisms dependent on each other for survival?

Organisms are dependent on each other for survival because they rely on other organisms for food, shelter, and other resources necessary for their survival. Without these interactions, many organisms would struggle to meet their basic needs.

Q: How do organisms interact with non-living components of the environment?

Organisms interact with non-living components of the environment, such as water, air, and soil, by utilizing them for their survival. For example, plants obtain water and nutrients from the soil, while animals breathe in oxygen from the air. These non-living components are essential for the functioning of ecosystems.

Q: What happens if one component of the environment is disrupted or absent?

If a component of the environment is disrupted or absent, it can have significant consequences on the survival of organisms. For example, if there is a shortage of water, both plants and animals will struggle to survive and may even die. Disruptions in the ecosystem can lead to imbalances and negatively impact populations and overall biodiversity.

Q: How do interactions between organisms affect populations?

Interactions between organisms directly influence population dynamics. For instance, if a predator population increases, it can lead to a decrease in prey populations. Similarly, if a species that plays a vital role in the ecosystem becomes extinct, it can have cascading effects on other populations and the overall balance of the ecosystem.
