ANSWER ALL QUESTIONS
******************The following questions are based upon 2 different food webs.

Questions and Answers

1.

What animal listed below is the highest order consumer in this food web?
- A.
  
  Seal
- B.
  
  Penguin
- C.
  
  Krill
- D.
  
  Blue whale
Correct Answer
A. Seal

Explanation
The seal is the highest order consumer in this food web because it preys on penguins, which are lower in the food chain. The seal is at a higher trophic level as it consumes animals that are themselves consumers of other organisms. The krill and blue whale are not higher order consumers as they primarily feed on lower trophic level organisms such as plankton.

Rate this question:
2.

Which of the groups listed below is the complete list of Krill predators?
- A.
  
  Penguin, Squid, Seagull
- B.
  
  Blue whale, Penguin, Squid
- C.
  
  Seal, Blue Whale, Seagull, Squid.
- D.
  
  Plankton, Krill, Squid, Seagull
Correct Answer
C. Seal, Blue Whale, Seagull, Squid.

Explanation
The correct answer is Seal, Blue Whale, Seagull, Squid. Krill are small crustaceans that make up a significant part of the diet for many marine animals. Seals, blue whales, seagulls, and squids are all known to be predators of krill. Penguins are also krill predators, but they are not included in this answer choice. Plankton and krill are not predators but are actually part of the prey base for many marine animals. Therefore, the correct answer is Seal, Blue Whale, Seagull, Squid.

Rate this question:
3.

For the following food chain what order consumer is the Squid? Plankton --> Krill --> Squid --> Penguin --> Seal
- A.
  
  3rd
- B.
  
  4th
- C.
  
  2nd
- D.
  
  1st
Correct Answer
C. 2nd

Explanation
The squid is the second order consumer in this food chain. It feeds on the krill, which is the first order consumer that consumes the plankton. The penguin, which is the third order consumer, feeds on the squid. The seal, which is the fourth order consumer, feeds on the penguin. Therefore, the squid is the second order consumer in this food chain.

Rate this question:
4.

As the producer of all food chains shown here the Plankton has the largest population. Which of the following is most likely to have the next largest population in this food web?
- A.
  
  Krill
- B.
  
  Penguins
- C.
  
  Seagulls
- D.
  
  Squid
Correct Answer
A. Krill

Explanation
The Krill should be expected to be the largest as it is a food source for many other species.

5.

The Penguin has 2 food sources in this food web. Select the group below that correctly represents the Penguins diet.
- A.
  
  Plankton and Krill
- B.
  
  Krill, Squid and Plankton.
- C.
  
  Squid and Plankton
- D.
  
  Squid and Seagull
Correct Answer
C. Squid and Plankton

Explanation
The correct answer is Squid and Plankton. This is because the question states that the Penguin has 2 food sources, and the only option that includes both Squid and Plankton is Squid and Plankton. Therefore, Squid and Plankton represent the Penguin's diet.

Rate this question:
6.

Which of the terms below best describe the important component that is missing from this food web?
- A.
  
  Bacteria
- B.
  
  Fungi and other bugs
- C.
  
  Decomposers
- D.
  
  Fungi
Correct Answer
C. Decomposers

Explanation
Decomposers are organisms that break down dead organic matter and recycle nutrients back into the ecosystem. They play a crucial role in the food web by decomposing dead plants and animals, releasing nutrients that can be used by other organisms. Without decomposers, the ecosystem would be unable to efficiently recycle nutrients and sustain life. Therefore, the term "decomposers" best describes the important component that is missing from this food web.

7.

Which of the consumers listed below eat only one food?
- A.
  
  Honeyeater
- B.
  
  Grasshopper
- C.
  
  Kangaroo
Correct Answer
C. Kangaroo

Explanation
The correct answer is Kangaroo because it is the only consumer listed that eats only one food. Honeyeaters are known to eat nectar, insects, and fruits, while grasshoppers are herbivores that eat grass and other plants. Kangaroos, on the other hand, are grazers that primarily eat grass and other vegetation, making them the only consumer on the list that has a single food source.

Rate this question:
8.

From where do the eucalypt, wattle and native grass gain their energy?
- A.
  
  Sun
- B.
  
  Moon
- C.
  
  Honey eater
- D.
  
  Grasshopper
Correct Answer
A. Sun

Explanation
Producers receive their energy from the sun via photosynthesis.

Rate this question:
9.

The lizard is a food source for the greater range of predators. Which of the following terms best describes the relationship between these predators?
- A.
  
  Mutualism
- B.
  
  Commensalism
- C.
  
  Competition
- D.
  
  Predation
Correct Answer
C. Competition

Explanation
The correct answer is competition because the statement suggests that the predators are competing for the food source provided by the lizard. This implies that they are in direct competition with each other to obtain the limited resources available.

Rate this question:
10.

For the Food Web shown here select all of the producers.
- A.
  
  Eucalyptus
- B.
  
  Native Grass
- C.
  
  Honey Eater
- D.
  
  Wattle Tree
- E.
  
  Grasshopper
Correct Answer(s)
A. Eucalyptus
B. Native Grass
D. Wattle Tree

Explanation
The correct answer includes Eucalyptus, Native Grass, and Wattle Tree. Producers in a food web are organisms that can produce their own food through photosynthesis or chemosynthesis. Eucalyptus and Wattle Tree are both plants, which are known as primary producers because they can convert sunlight into energy through photosynthesis. Native Grass also falls into this category as it is a type of plant. Grasshopper and Honey Eater are not producers as they cannot produce their own food and rely on consuming other organisms for energy.

Rate this question:
11.

For the Food Web shown here and from the list below, select all of the predators that feed on the grasshopper.
- A.
  
  Ant
- B.
  
  Honey Eater
- C.
  
  Spider
- D.
  
  Fantail
- E.
  
  Kangaroo
Correct Answer(s)
B. Honey Eater
C. Spider
D. Fantail

Explanation
The grasshopper is a prey species in the food web, meaning it is hunted and eaten by other organisms. The honey eater, spider, and fantail are all predators that feed on the grasshopper. These predators are higher up in the food chain and rely on consuming the grasshopper as a source of food. The ant and kangaroo are not predators of the grasshopper in this particular food web.
