Energy and Ecosystems
What are the parts of a plant and their functions?
Plant Structures
Living things interact with one another in the environment.

Energy flows from the sun to plants and animals.

Organisms compete and survive in an ecosystem.

Ecosystems change over time.

People affect ecosystems.
What does a plant need for photosynthesis?
Consumers and Producers
Animals can't make their own food, but they need energy from food to survive. when animals eat plants,the animals receive the energy that's stored in those plants. the word comprise means to eat so we call animals that eat so we call animals that eat plants or animals consumers.

How do organisms compete and survive in an ecosystem?

Ecosystems and Change
Interactions in Nature
In most of the ecosystems there are plants and animals. All organisms of one kind in an ecosystem are called a population, for example:
A pond ecosystem, it might have populations of frogs,waterlilies,insects,duckweed,and protist.
Populations living and interacting with each other form a community. Another part of an ecosystem is the physical environment. An adaptation is a characteristic that helps an organism to complete in an ecosystem.A turtle survives in the winter by burrowing into the mud. This characteristic is an adaptation.
How do organisms compete and survive in an ecosystem?
Ecosystems and Change
Symbiosis: There are 3 types of Symbiosis, the first one is called Mutualism, where the and the ant help each other. The other one is called Comensalism. In that only one orginism benefits- whitch is the Remora not the shark.
Parasitism- One benefits and the other one is harmed.

Ecosystems and Change
Predator-Prey Relationships
Pretadors and prey need to survive.
Predators need prey and prey also need predators.
Prey need predators because if ther is a lot of prey, they don't have enough food.
Predators need prey to eat and survive.
We know that every single organism needs to survive.

Ecosystems and Change
Restoring ecosystems
is all about repairing damaged or destroyed ecosystem. The restoration of ecosystems is the most important thing of all, because if there wasn't restoring ecosystems there wouldn't be any ecosystems. When you say restore an ecosystem you say repair an ecosystem.

Removing pollutants is one way to restore ecosystems. In the United States, they lost most of the wetlands, which help filter pollutants out of water. But now, they are trying to restore more wetlands because they learned how important they are.

If we restore ecosystems, our ecosystems will never be lost!

Ecosystems also represent an exceptional source of outdoor recreation opportunities. Ecosystems are part of our lifes. they give us food they give us fresh air to breath with, even fresh water. sometimes we use ecosystems to play with. Out door expiriences to make. Thats way ecosystems are inportant and why we should help ecosystems like they have done to us. Meany laws have been spread to try to stop Ecosystems from being destroyed.
Natural Cycles
Tertiary Consumers =Top Predator & Secondary Carnivores = The Jaguar
Secondary Consumers = Carnivores (Meat Eating animals) = Mountain Gorilla
Consumers = Herbivores = Plant Eating Insects
Producers = plants
An energy pyramid shows that each level of a food chain passes on less food energy than the next level.the second carnivore has plants, bugs, and gorilla in the jaguar´s stomach. they have lots of energy.
The first part starts with producers, then first-level consumer. Next, is the second-level consumer and on top, goes the third-level consumer.
A food web shows the relationships among different food chains.
There are two types of food web prairie and pond
Food web have carnivores which eat meat, herbivores which eat plants and omnivores eat both.
An example of a food web is, a hawk eats a mouse that mouse ate seeds.
Consumers and Producers
Ecosystems and Change
Plants are called producers because they produce their own food .The word consume means to eat so we call animals that eat plants or other animals consumers.

Can you think of examples of each?
Nitrogen cycle is a gas cycle. First the gas is in the air then when a lighting strikes it changes it so that plants can use it. Then animals eat plants and the nitrogen comes out. Then it happens all over again.
How do Ecosystems Change Over Time?
Damaging Ecosystems
If we destroy Ecosystems the world won’t be same because we would have acid rains, pollution, and less oxygen. Pollution means when a living thing dies and contaminates the places that it died close to so that is why when something dies we have to take it out or it pollutes the whole world.. Those places are called habitats the habitats is where the animals live some of them are ocean, desert and forest. And acid rain means when instead to fall water it falls rain.
