B9 Habitats Flashcards
These flash cards are on Living things in their environment (habitats). You need to be familiar with page 16-17 of 'Ard Facts.
In a food chain, the type of organism which uses energy from the sun is a…
Producer
A primary consumer is likely to eat a…
Producer
Herbivores feed on…
Producers only
Carnivores feed on…
Consumers only
Omnivores feed on…
Producers and consumers
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.
The population of Pike would reduce because there is less food available.
Animals that are active only at night are said to be…
Nocturnal
In order to find feeding or breeding grounds an animal may…
Migrate
If there are 10 daisies growing in an average square metre of lawn, how many daisies are there in total if the area of the lawn is 40 square metres?
10 per square metre X 40 = 400 daisies
The population of daisies on a lawn could be best measured with…
A quadrat
It’s a square grid that can be placed at random in your habitat to count different species.
Explain why it is important for farmers to control the amount of pesticides sprayed on crops.
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!
Name a habitat you have studied and name two physical factors that you have measured.
Clue: Physical factors are things like temperature, availability of water, soil pH (how acidic or alkaline) and light intensity.
Suggest a plant from your habitat whose population is affected by competition. Name the other animals or plants involved.
For example: The population of ______ is affected by competition with ____ for _____
Name an animal you have studied and suggest how it adapts to seasonal changes in the environment (over a year).
For example, an animal that hibernates or migrates to make the best of the weather or food availability.
Name a plant you have studied and suggest how it adapts to daily changes in the environment.
For example, many plants react to light by moving or protecting their flowers at night.
Suggest an animal from your habitat whose population is affected by predation. Name the predator.
For example: The population of ______ is affected by predation from _____
Complete this food chain using these organisms: newt, pond weed, heron
_________ —> tadpole —> _________ —> _________
Pond weed –> tadpole –> newt –> heron
In a habitat, pike feed on trout and perch. If the perch were removed, what would be the effect on trout?
The population of trout would reduce due to extra predation from pike.
Complete this food chain using these organisms: fox, grass.
__________ —> rabbit —> __________
Grass –> rabbit –> fox
Choose one animal from a habitat you have studied and suggest two ways in which it is suited to life there.
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?
Name a herbivore from a habitat that you have studied.
Clue: herbivores only eat producers (plants).
Describe how you would measure the population of beetles living on a large lawn.
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.
Explain why it is important for farmers to control the amount of pesticides sprayed on crops.
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.
Suggest a plant from your habitat whose population is affected by predation. Name the predator.
For example: The population of ______ is affected by predation from _____
Suggest an animal from your habitat whose population is affected by competition. Name the other animals or plants involved.
For example: The population of ______ is affected by competition with ____ for _____
Name an omnivore from a habitat that you have studied.
Clue: omnivores eat both producers (plants) and consumers (animals).
Name a carnivore from a habitat that you have studied.
Clue: carnivores eat only consumers (animals).
What is a habitat?
It is the home or environment of a living thing.
Name a plant you have studied and suggest how it changes over 12 months.
For example, many plants make and disperse seeds which survive over the winter. Some plants store food underground to use in spring.
Explain why most food chains start with a producer.
Producers (plants) get energy from the sun. Consumers (animals) depend on producers for all their energy needs.
Write down a food chain including at least three organisms from a habitat you have studied.
Don_t forget to start with a producer (plant). The arrow means ‘gets eaten by’.
Name a habitat you have studied and suggest how the environment changes over 24 hours.
Ideas: variations in light, temperature.
Name a habitat you have studied and suggest how the environment changes over 12 months.
Ideas: variations in climate, day length.
Name an animal you have studied in its habitat and suggest how its population varies over 12 months.
For example: The population of ______ rises during spring and falls during the winter.
Name a plant you have studied and suggest how it adapts to seasonal changes in the environment (over a year).
For example, many plants make and disperse seeds which survive over the winter. Some plants store food underground to use in spring.
Name an animal you have studied and suggest how it adapts to daily changes in the environment.
For example, some animals are nocturnal. Some hunt only at dusk or dawn.
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?
The lawn is 5 m X 10 m = 50 square metres.
9 per square metre X 50 = 450 daisies
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.
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
