GRASSLANDS STEP 1

----------------------------------

BIOTIC STEP 2

-Long grass, little trees, shrubs, wildflowers, buffalo, prairie dogs

ABIOTIC  

-Sunlight is very harsh, temperature is hot in the summer cold in the winter, rain is moderate,water usually running in a stream, rocks and soil capable of growing wheat.

----------------------------------

CARRYING CAPACITY STEP 3

Carrying capacity is the maximum number of a species that an environment can hold.

Cheetahs have changed over time like many other species. Female cheetahs learned to mate with many males making the population larger and so the cubs have a variety   Zebras have also changed over time. There stripes make it harder for the predators to make out their bodies outline helping the herd in lots of ways.  

----------------------------------

LIMITING FACTORS STEP 4

A factor that limits the growth of a population such as an abundance of food.

Predator Prey                                                                                                                  A cheetah hunts down a zebra and if there aren't many zebras that year then there won't be enough food for the cheetah so they will have to fight for food. They might have to fight lions or even other cheetah to get enough food.

----------------------------------

ENERGY ROLES STEP 5

Producer: A producer is an organism that is always at the bottom of the food chain that instead of eating other organisms for food it makes its own through photosynthesis. ex. Grass, trees, and shrubs

Herbivore: A herbivore is an organism that is usually the primary consumer that only eats plants for its energy source. Ex. Zebras, antelopes, and buffalo

Carnivore: A carnivore is an organism that is either a secondary or higher consumer that eats other organisms for energy. Ex. Lion, cheetah, anteater.

Omnivore: An omnivore is an organism that eats plants or animals for energy located at any of the levels beside producers.

Producers are vital to every ecosystem because it is the main way for all animals to get energy. Without plants there would be no herbivores, no herbivores no carnivores or omnivores.

----------------------------------

FOOD CHAINS FOOD WEBS STEP 6

Food webs are more realistic than food chains because predators don't only eat one kind of prey they eat multiple animals.

If you removed one type of animal then the whole food web would die out or find another organism to eat.

----------------------------------

FOOD PYRAMID STEP 7

The energy pyramid is shaped like a pyramid to show that as you go up the pyramid the less energy there is supporting less organisms.

The pyramid is larger at the bottom because there is more organisms and energy.

----------------------------------

PHOTOSYNTHESIS 6CO2+6H20 -> C6+H12+O6 STEP 8

For photosynthesis carbon dioxide, sunlight, water. It produces glucose, food for plants. It is like sugar and during photosynthesis oxygen is made, the air we breathe.

-----------------------------------

TROPISM STEP 9
A turning of an organism due to an external stimulus.

You might find tropism in a grassland when a plant, such as a sunflower, moves toward the light or when a plant moves in the direction of water.

This image is an example of phototropism because you can see that the plants grew in th way that the sun set, the last time the plants saw the sun.

This helps them survive because then they get enough sunlight to help them grow and thrive to get the consumers enough energy.

-----------------------------------

DECOMPOSERS STEP 10

Decomposers are vital to all ecosystems because without them then when animals and plants die there wouldn't be any energy going back to the plants resulting, sooner or later, there wouldn't be enough energy.

In a grasslands the main decomposers are earthworms, fungi, bacteria, and some insects.

-----------------------------------

ADAPTATIONS STEP 11

Adaptations help an organism survive by adapting to the environment they live in. For example, elephants learned to live in herds and to make a circle around young in order to protect them.

If an animal was placed in a different environment then it would have to adapt in order to survive. It would have to also find a new food source.

-----------------------------------

NATURAL SELECTION STEP 12
Natural selection is when an animal with a certain kind of trait is lost to the more useful trait.   

Natural selection is important because if it didn't ever occur then some species would've died out many years ago.

The antelope is an example of natural selection. It occurred when the land started to become more open and the cheetah became faster, resulting in either being faster or death. The faster antelope survived but the slow eventually died out.

As you can see the antelope now have longer, leaner, and faster bodies to out-run the cheetah.
