HOW DO ORGANISMS COMPETE AND SURVIVE IN AN ECOSYSTEM
31
The END
Parasitism
One benefits but the other is affected
Example
The tapeworm eats the food from human.
It benefits but human is affected
What can we do?
Conservation: use less resources
or saving resources in which there are the three "R" Reuse, reduce and recycle.
Reclamation
Another way we can help the ecosystems is to do reclamation that is to clean and restore the ecosystems
Community
It is when populations interact
Food
Acid rain
When we burn fossils, the gases mix with water
vapor in the clouds, it forms acid
and falls in form of rain, sleet or snow. Acid rain can damage trees, plants, fish, water, animals or us.
Damaging ecosystems
Humans made pollution which
changes ecosystems (bad changes)
humans made chemicals that pollute water. Also we
throw trash which animal can find, cut them or eat
them and die. Another thing is that we destroyed
animals`s habitats
When we burn fossils fuels, it can make acid rain.
Space
What do populations in an ecosystem
need to survive
Water
Example:
Humans breathe out carbon dioxide then the plants absorb it, then release oxygen so we can breathe
Mutualism
Both are benefit
Symbiosis
There are 3 kinds
A relationship between different
kinds of organisms.
These animals compete for food
Shelter
Competition
Is like a contest between organisms
in an ecosystem to reach their needs
Commensalism:
One animal benefits and the other is not afected
Example
The Killdeer Bird lies down on the buffalo and the buffalo protects the Bird. But the bird does not harm the buffalo. Birds benefit, but Cape Buffalo is not affected.
Population
All organisms of one kind
in an ecosystem
Sometimes there is not food for
all orgnisms so organisms need to compete with each other to reach their needs.
