Adapation Flashcards
How are animals adapted to cold environments
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
What are adaptions
Special features that allow animals to survive in particular environments
How are animals adapted to hotter climates
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
How do plants lose water
Through transpiration and evaporation and through the stomata
How are plants adapted to surviving with little water in the desert
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
How are cacti adapted to collects and prevent the loss of water
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
What are the features of curved leaves that help reduce water loss
They have small surface area
They trap moist air around the plant to reduce water loss by evaporation
What features do plants have to deter animals away
Some have spines and thorns to prick animals
Some produce Poisons
What do animals compete for
Food,territory,mates
What are herbivores
Animals that only eat plants and grass
What are carnivores
They feed on meat
Where is competition among animals more likely
Among carnivores
What features can make predators successful
They have adapted long legs to run fast
Sharp eyes to spot prey
How do prey adapt to being unseen
They are camouflage and have good hearing to flee
Which animals who compete are most likely to survive
The ones which are best adapted to their environment
How do animals find mates
They fight each other for a female
They try and show off for a female
What is a territory
An area where animals can feed and live and look after resources
What do plants compete for and why
Light - for photosynthesis
Water- for photosynthesis and too keep cells rigid
Mineral- to make vital chemical for cells
Why do seeds need to spread out over a suitable distance
As of not the parent plant deprives the other seedlings of the essentials needed to grow
How do small plants in forests compete
They have roots adaptions to retrieve water
In the shade of other plants they grow taller and there leaves have a larger surface area
What type of roots do some leaves have
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
What are the ways in which seeds are distributed
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
In fields which seeds are most likely to be successful
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
