Interdependence and adaption Flashcards
What is camouflage used for?
To blend in with the environment
What are adaptions?
A feature or behaviour that helps an organism to survive in their habitat
What is insulation used for?
To control heat loss
What does a large surface area to volume ratio do?
Increases heat loss
What does a small surface area to volume ratio do?
Reduces heat loss
Why do animals adapt their shape?
To be streamlined for movement in air or water
Name some adaptions of the camel
Fat stored in one place to it doesn’t insulate the heat, two sets of eyelashes to keep sand out of eyes, fat can release water, hooves to stop feet touching ground, big feet so they don’t sink, long legs to keep body away from hot sand, two toes to walk on sand that moves, big surface area to volume ratio to increase heat loss, hump metabolised to release energy
Name some adaptions of the polar bear
Small ears to reduce heat loss, black skin to absorb heat, good sense of smell to find prey, fat and fur to insulate and reduce heat loss, sharp teeth to catch and kill prey, hairs on bottom of feet for grip, sharp claws and big paws to catch and kill prey, white fur for camouflage, hairs are hollow to insulate, small surface area to volume ratio to reduce heat loss
What are the mean four ways plants adapt?
Change surface area of leaves, have water-storage tissues, have deep or widespread roots, have thorns or toxins
What 4 things do animals compete for?
Food, water, territory, mates
What 4 things do plants compete for?
Light, water, space, minerals
What is interspecific competition?
When different species compete against each other
What is intraspecific competition?
When organisms of the same species compete against each other
What are some factors affecting the distribution of organisms and how do you measure them?
Disease, pH (pH meter), loss of habitat, light levels (light meter), water pollution/O2 levels (invertebrates), rainfall (rain gauge), air pollution/SO2 levels (lichen), predators, competition, temperature (thermometer), CO2/O2 levels (CO2/O2 meter), food supply
What are stomata?
Tiny pores, usually found on the underside of leaves, they allow gas exchange (CO2/O2) but also result in water loss
