Q

In a habitat, pike feed on trout and perch. If the trout were removed, what would be the effect on pike? Use the words ‘the population of pike’ in your answer.

A

The population of Pike would reduce because there is less food available.

Q

Explain why it is important for farmers to control the amount of pesticides sprayed on crops.

A

Pesticides may get inside animals and plants but not always kill them.
The chemicals get passed up the food chains.
Animals at the top of the food chain can get a concentrated dose of the chemicals, which can be harmful.
We are at the top of many food chains!

Q

Suggest an animal from your habitat whose population is affected by predation. Name the predator.

A

For example: The population of ______ is affected by predation from _____

17
Q

Complete this food chain using these organisms: newt, pond weed, heron

_________ —> tadpole —> _________ —> _________

A

Pond weed –> tadpole –> newt –> heron

18
Q

In a habitat, pike feed on trout and perch. If the perch were removed, what would be the effect on trout?

A

The population of trout would reduce due to extra predation from pike.

19
Q

Complete this food chain using these organisms: fox, grass.

__________ —> rabbit —> __________

A

Grass –> rabbit –> fox

20
Q

Choose one animal from a habitat you have studied and suggest two ways in which it is suited to life there.

A

Think of an adaptation of that plant that makes it suited to the habitat. Does it grow fast, is it poisonous, is it capable of growing very tall?

21
Q

Name a herbivore from a habitat that you have studied.

A

Clue: herbivores only eat producers (plants).

22
Q

Describe how you would measure the population of beetles living on a large lawn.

A

Place a quadrat randomly on the lawn several times.
Count the number of beetles in an average square metre.
Multiply the average by the area of the lawn.

23
Q

Explain why it is important for farmers to control the amount of pesticides sprayed on crops.

A

Pesticides may get inside animals and plants but not always kill them.
The chemicals get passed up the food chains.
Animals at the top of the food chain can get a concentrated dose of the chemicals, which can be harmful.

24
Q

Suggest a plant from your habitat whose population is affected by predation. Name the predator.

A

For example: The population of ______ is affected by predation from _____

25
Q

Suggest an animal from your habitat whose population is affected by competition. Name the other animals or plants involved.

A

For example: The population of ______ is affected by competition with ____ for _____

26
Q

Name an omnivore from a habitat that you have studied.

A

Clue: omnivores eat both producers (plants) and consumers (animals).

27
Q

Name a carnivore from a habitat that you have studied.

A

Clue: carnivores eat only consumers (animals).

28
Q

What is a habitat?

A

It is the home or environment of a living thing.

29
Q

Name a plant you have studied and suggest how it changes over 12 months.

A

For example, many plants make and disperse seeds which survive over the winter. Some plants store food underground to use in spring.

30
Q

Explain why most food chains start with a producer.

A

Producers (plants) get energy from the sun. Consumers (animals) depend on producers for all their energy needs.

31
Q

Write down a food chain including at least three organisms from a habitat you have studied.

A

Don_t forget to start with a producer (plant). The arrow means ‘gets eaten by’.

32
Q

Name a habitat you have studied and suggest how the environment changes over 24 hours.

A

Ideas: variations in light, temperature.

33
Q

Name a habitat you have studied and suggest how the environment changes over 12 months.

A

Ideas: variations in climate, day length.

34
Q

Name an animal you have studied in its habitat and suggest how its population varies over 12 months.

A

For example: The population of ______ rises during spring and falls during the winter.

35
Q

Name a plant you have studied and suggest how it adapts to seasonal changes in the environment (over a year).

A

For example, many plants make and disperse seeds which survive over the winter. Some plants store food underground to use in spring.

36
Q

Name an animal you have studied and suggest how it adapts to daily changes in the environment.

A

For example, some animals are nocturnal. Some hunt only at dusk or dawn.

37
Q

If there are 9 daisies growing in an average square metre of lawn, how many daisies are there in total if the rectangular lawn measures 5 m by 10 m?

A

The lawn is 5 m X 10 m = 50 square metres.

9 per square metre X 50 = 450 daisies

38
Q

Using a quadrat a gardener counts the number of dandelion plants growing in random square metres on her lawn. 1st count: 9 plants, 2nd count: 14 plants, 3rd count: 13 plants.
Predict how many dandelions there are in total if the rectangular lawn measures 5 m by 8 m. Show your working.

A

Average per square metre = (9+14+13) divided by 3 = 12 dandelions

Lawn area = 5 m X 8 m = 40 square metres

Total = 12 per metre X 40 = 480 dandelions
