Interactions In An Ecosystem

1.

A ____________ is a type of consumer that gets its food by breaking down animal wastes and the remains of dead plants and animals.

Explanation
A decomposer is a type of consumer that obtains its food by breaking down animal wastes and the remains of dead plants and animals. They play a crucial role in the ecosystem by breaking down organic matter and recycling nutrients back into the environment. Decomposers, such as bacteria, fungi, and certain types of insects, help to break down complex organic compounds into simpler forms that can be absorbed by other organisms. Without decomposers, dead organisms and waste materials would accumulate, and the nutrient cycle would be disrupted.

An animal that feeds on other living animals is called a _________________.

Explanation
A predator is an animal that hunts and feeds on other living animals. Predators have adaptations such as sharp teeth, claws, and keen senses that help them catch and kill their prey. They play a crucial role in maintaining the balance of ecosystems by controlling the population of prey species. Predators can be found in various habitats, ranging from forests to oceans, and they exhibit a wide range of hunting strategies and behaviors. Overall, a predator is an essential component of the food chain and plays a vital role in the natural world.

3.

The animals that predators eat are called _____________.

Explanation
Predators feed on other animals for survival, and the animals they consume are referred to as prey. Prey are typically smaller or weaker than the predators, and they serve as a source of food for the predators. This relationship is a fundamental aspect of the food chain, where predators play a crucial role in maintaining the balance of ecosystems by controlling the population of prey species.

_____________ is a relationship between two organisms of different species that benefits one or both of the organisms, it means "living together".

Explanation
Symbiosis is a relationship between two organisms of different species that benefits one or both of the organisms. This relationship is often referred to as "living together." In symbiosis, the organisms rely on each other for survival, with each providing something that the other needs. This mutually beneficial interaction can involve various forms, such as mutualism, where both organisms benefit, or commensalism, where one organism benefits while the other is unaffected. Symbiosis plays a crucial role in maintaining ecological balance and promoting species coexistence.

A barn owl is -
- A.
  
  A.both a producer and predator
- B.
  
  Both producer and prey
- C.
  
  Both consumer and predator
Correct Answer
C. Both consumer and predator

Explanation
A barn owl is both a consumer and a predator. As a consumer, it feeds on other organisms for energy and nutrients. Barn owls primarily consume small rodents such as mice and voles. As a predator, the barn owl hunts and captures its prey using its excellent hearing and night vision. It plays an important role in controlling rodent populations, making it a valuable predator in ecosystems.

In the symbiosis between a virus and and a human, the human is-
- A.
  
  The host
- B.
  
  The parasite
- C.
  
  The prey
Correct Answer
A. The host

Explanation
In the symbiotic relationship between a virus and a human, the human is referred to as the host. This is because the virus depends on the human to provide the necessary environment and resources for its survival and reproduction. The human, on the other hand, may be negatively affected by the virus, experiencing symptoms and potential harm, making it the host of the virus.
