Chapter 4-living Things In Their Enviroment Flashcards
Define habitat
A place for plantar animal lives
Describe a rain forests conditions, edit Tatian’s of a plant, adaptations of an animal living in a forest
Conditions, hot and humid, sunlight top, dark on floor
Adaptations of plants, trees leafy at top, plants on floor make food lowlight or grab sides of trees for light
Adaptations of animals monkeys balance, jump and climb food, frogs Have sticky feet so that they space have sticky feet so that they can climb trees
Defined the conditions in a desert and the adaptations of plants and animals that live in a Desert
Conditions, hot and day cold at night, short period of rainfall in to Well drained soil
Adaptations of plants, cactuses thick waxy skin prevent water loss and long routes to find water deep in soil, plants grow flowers and sits in quickly after ride
Adaptations of animals, borrow to hide from heat and cold conserve water in bodies by releasing small amounts of urine, tough mouth to feed on plants, wide feet to prevent sinking in sand
Define the conditions of a river, adaptations of plants and animals living in the river
Conditions, water that is moving
Adaptations of plants, Plants can take in carbon dioxide dissolved in water as well as minerals through stem and leaves, roots whole plant in mud, and floppy stems as water support support
Adaptation of animals, fish have gills, shape to move through water, leeches have suckers told on in currents
Define a food chain
The food chain shows the path of food and energy it contains through a series of organisms as one feeds on another
Where is the energy of almost all food chains come from
The sunAs plants need sun and plants are usually start of the food chain
What do decomposers do
They break down a plant or animal when it dies
What are the two major factors which affect population size
The birthright, and the death rate
What is the population of a species In habitat
Population of a species in habitat is the number of individuals of That species which are present
What are the positive and negative influences of energy on humans
Positive, wind, water, and solar sources, using energy savings schemes and Using Methane from wastes fuel
Negative, using fossil fuels can increase carbon dioxide in air and may increase global warming, acid rain
Are the negative and positive influences of pollution on humans
Positive, reducing carbon dioxide omissions, limiting pesticides and fertilizers, recycle to reduce the need of landfill sites
Negative, the same as carbon dioxide negative influences, oil spillage is Pollute seas
What are the positive and negative affects of materials on humans
Positive, recycling to reduce the need to extract more from the earth and to conserve for the future
Negative, Mining destroy habitats
What are the positive and negative Influences of habitats on humans
Positive, creating national parks wildlife prevents habitat destruction
Negative, towns, cities and farms destroy habitats
State some nonrenewable Resources
Fossil vehicles, coal, oil and natural gas methane
Why is nuclear fuel bad for the earth
It contains radioactive materials such as re-uranium, it could leak radioactive material which can cause environmental damage
