Do you know what is a food chain? A food chain is a straight network of links in a food web starting from producer organisms and ending at apex predators, detritivores, or decomposer species. A food chain also shows how organisms are related to others by the food they eat. Each level of a food chain represents various trophic levels.

Questions and Answers

1.

WHAT IS THIS CALLED?
- A.
  
  Animals order
- B.
  
  Food chain
- C.
  
  Types of animals
- D.
  
  Option 4
Correct Answer
B. Food chain

Explanation
The correct answer is "food chain" because it refers to the sequence of organisms in an ecosystem, where each organism is the source of food for the next organism in the chain. It helps to understand the flow of energy and nutrients in an ecosystem and how different organisms depend on each other for survival.

The food chain must start with plants.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Plants are the primary producers in a food chain as they convert sunlight into energy through photosynthesis. They are the source of food for herbivores, which are then consumed by carnivores, and so on. Without plants, there would be no energy input into the food chain, and the other organisms in the chain would not be able to survive. Therefore, the food chain must start with plants.

The rabbit is a meat eater.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement says that the rabbit is a meat eater, but this is incorrect. Rabbits are herbivores, which means they primarily eat plants and do not consume meat. They have a specialized digestive system that is adapted for breaking down plant material. Therefore, the correct answer is false.

The ...................is a tiny organisms that live in the sea.
- A.
  
  Plankton
- B.
  
  Minnows
- C.
  
  Starfish
- D.
  
  Option 4
Correct Answer
A. Plankton

Explanation
Plankton refers to a group of tiny organisms that inhabit the sea. They are unable to swim against the current and are carried along by water movements. Plankton serves as a vital food source for many marine animals and plays a crucial role in the ocean's ecosystem. Therefore, the given answer, "plankton," accurately describes the tiny organisms that live in the sea.

The Great Horned Owl is an apex predator.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The Great Horned Owl is considered an apex predator because it is at the top of its food chain and has no natural predators. It has excellent hunting skills, including its ability to fly silently and its strong talons for catching and killing prey. Its large size and sharp beak also contribute to its success as a predator. As a result, it plays a crucial role in maintaining the balance of the ecosystem by controlling populations of small mammals and other prey species.

Any animal that is on top of the food chain is called an __________.

Correct Answer
Apex Predator

Explanation
An animal that is on top of the food chain and has no natural predators is known as an apex predator. These animals play a crucial role in maintaining the balance of ecosystems by controlling the population of other species in the food chain. They are typically at the highest trophic level and have adaptations that allow them to hunt and consume a wide range of prey. Examples of apex predators include lions, sharks, and eagles.

- The definition of “_________” is a model of food chains that intersect and show what eats what.
Correct Answer
food web

Explanation
A food web is a model that represents the interconnectedness of food chains and illustrates the relationships between different organisms and what they eat. It shows the flow of energy and nutrients through an ecosystem, depicting the various feeding relationships and interactions among different species. This model helps to understand the complex dynamics of ecosystems and how changes in one population can affect others.

Which of these is an apex predator?
- A.
  
  Lion
- B.
  
  Deer
- C.
  
  Catfish
- D.
  
  Tortoise
Correct Answer
A. Lion

Explanation
An apex predator is a predator that is at the top of the food chain and has no natural predators of its own. Lions fit this description as they are powerful and skilled hunters, capable of taking down large prey such as wildebeest and buffalo. They are not preyed upon by any other animal in their natural habitat, making them an apex predator. Deer, catfish, and tortoises are not apex predators as they are either herbivores or lower in the food chain, being preyed upon by other animals.

Which of these is a decomposer?
- A.
  
  Protozoa
- B.
  
  Amoeba
- C.
  
  Salmonella
Correct Answer
A. Protozoa

Explanation
Protozoa is a correct answer because decomposers are organisms that break down dead organic matter into simpler substances. Protozoa are microscopic single-celled organisms that feed on dead organic material, such as dead plants and animals. They play a crucial role in the decomposition process by breaking down complex organic compounds into simpler forms, which can then be recycled back into the ecosystem. Amoeba is a type of protozoa, but Salmonella is a pathogenic bacterium that causes food poisoning and is not involved in decomposition.
