5.1 Living places
Adaptions
-
Plants growing in dense rainforests often have long thin thread called tendrils to help them climb over other plants to reach the sunlight.
The quoll has many adaptions which help survive such as sharp claws and teeth to catch live rats, birds and reptiles
Adaptions enable animals to:
. Protect themselves from predators(camouflage)
. Survive hot and cold temperatures, and wet and dry seasons
. Move from place to place
. Catch and eat food
.Take in oxygen
.Reproduce
The spotted-tailed quoll is a marsupial that lives in the forests of eastern Australia, from Queensland to Tasmania
Crocodiles have adaptions that allow it to survive and reproduce such as dark patches along the sides and the upper body of the croc allow it to absorb heat from the sun
-
Adaptions enable plants to:
. Protect themselves from grazing animals
. Take in oxygen and carbon dioxide
. Take in water
. Capture light
. Reproduce
Living together
There is a relationship between the biosphere, ecosystems and habitats
-
An ecosystem is a system formed by organisms interacting with each other and their non-living surroundings in a balanced way
-
The biosphere is where all life as we know exists, the biosphere consists of the surface of the Earth and its atmosphere
The relationship between two different organisms can be positive, negative or have no impact on the individuals
Habitats
-
A habitat is where organisms live the habitat must provide everything that the organism needs to survive
-
-
All living things such as plants, animals and bacteria, are known as organisms
Habitat requirements
- Abiotic factors- these are non-living factors that include water, light, wind, soil and temperature
The number of organisms will depend on the availability of food, water, living space and mating partners
Needs of living things can be divided into two groups:
- Biotic factors- these are living factors that include partners for mating, organisms to eat, and organisms they may compete with for food
For an organism to survive the habitat must be able to provide
. Food
. Water
. Shelter and living space
. A suitable temperature
. Mating partners for reproduction
. Gases such as oxygen
Every living thing has particular needs, and will live only where these needs are met by the resources available in the habitat
Environmental conditions
-
Many factors may shape and change an environment, including:
. The temperature
. Whether it is wet or dry
. Whether it is windy
. The quality of the air
. The water quality
. The type of soil
. The plants, animals, bacteria and fungi that live there
