Adapation

Question 0

How are animals adapted to cold environments

Answer 0

Many animals have a small surface area and small ears that reduces the amount of heat they lose

They have large fat stores blubber that keeps them insulated and stops heat loss through the skin

The blubber acts as an source of food during winter months

Camflauge- this benefits both prey and predators

Question 1

What are adaptions

Answer 1

Special features that allow animals to survive in particular environments

Question 2

How are animals adapted to hotter climates

Answer 2

They have large surface area do heat is loss to prevent them overheating

Large ears to help them lose heat and cool then down

Thin layers of fat and fur so that they lose heat through skin easily

Many live in burrows under ground where temperature is cooler

Question 3

How do plants lose water

Answer 3

Through transpiration and evaporation and through the stomata

Question 4

How are plants adapted to surviving with little water in the desert

Answer 4

Leaves have a small surface area so that water loss is small(spines)

Some have curled leaves or spines

Many have roots underground which absorbs waters and stores it and succulents

Question 5

How are cacti adapted to collects and prevent the loss of water

Answer 5

They have spines which have small surface areas so small amounts water vapour is lost

They have succulents(green stem) and tissues that store water for the cacti

Spines to stop predators from eating them

Question 6

What are the features of curved leaves that help reduce water loss

Answer 6

They have small surface area

They trap moist air around the plant to reduce water loss by evaporation

Question 7

What features do plants have to deter animals away

Answer 7

Some have spines and thorns to prick animals

Some produce Poisons

Question 8

What do animals compete for

Answer 8

Food,territory,mates

Question 9

What are herbivores

Answer 9

Animals that only eat plants and grass

Question 10

What are carnivores

Answer 10

They feed on meat

Question 11

Where is competition among animals more likely

Answer 11

Among carnivores

Question 12

What features can make predators successful

Answer 12

They have adapted long legs to run fast

Sharp eyes to spot prey

Question 13

How do prey adapt to being unseen

Answer 13

They are camouflage and have good hearing to flee

Question 14

Which animals who compete are most likely to survive

Answer 14

The ones which are best adapted to their environment

Question 15

How do animals find mates

Answer 15

They fight each other for a female

They try and show off for a female

Question 16

What is a territory

Answer 16

An area where animals can feed and live and look after resources

Question 17

What do plants compete for and why

Answer 17

Light - for photosynthesis
Water- for photosynthesis and too keep cells rigid

Mineral- to make vital chemical for cells

Question 18

Why do seeds need to spread out over a suitable distance

Answer 18

As of not the parent plant deprives the other seedlings of the essentials needed to grow

Question 19

How do small plants in forests compete

Answer 19

They have roots adaptions to retrieve water

In the shade of other plants they grow taller and there leaves have a larger surface area

Question 20

What type of roots do some leaves have

Answer 20

Some have short and hollow roots do get water and nutrients close to the soil

Some have long deep roots to collect water deep underground

Question 21

What are the ways in which seeds are distributed

Answer 21

They can be distributed as waste from animals

Plant form mini explosions that spread the seeds out as far as possible

They are spread out by wind(sesame seeds)

some seeds contain hooks to hook onto animal fur and to be taken far from the plants
I

Question 22

In fields which seeds are most likely to be successful

Answer 22

The seeds that spread their roots out the first to gain access to water quickly

The ones that the leaves spread our first and the furthest in order to photosynthesise and gain enegry
