Temperate Grasslands

Biotic factors

Specific biotic factors in the grasslands would be the grasses like windmill grass, kangaroo grass, tall spear grass, weeping grass, nodding salt bush, native spear grass because their is an excessive amount of it.

Specific abiotic factors in the grasslands would be soil, dirt, and water because their is an excessive amount of it.

Animals

Aardvark, African buffalo, African wild dog, alpaca, anaconda, ant, anteater, antelope, baboon, buzzard, hawk, eagle, death addar, deer, moose, fox, rabbit.

Plants

windmill grass, kangaroo grass, tall spear grass, weeping grass, nodding salt bush, native spear grass, sticky everlasting, chocolate lily, lemon beauty heads, common cud-weed, plains flax lily.

Abiotic factors

Rocks, dirt, air, water, climate, temperature, soil.  

Carrying capacity

The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

The vulture population in my environment decrease and increase thus change over time; due to the amount of dead organisms for them to eat. There are many live organism and these organisms have plenty of resources so their are not many dead organisms for tese vultures.

My population needs:

shelter

space

food

water

prey

predators

A limiting factor in the grasslands are dead organisms for vultures to feed on.

predator/prey relationships

The predator/prey relationship is between snakes and a owl; both eat meat, primarily mice. Thus mice is a limiting factor for these two organisms.

Energy roles

Producers get energy through photosynthesis and without producers getting energy from the sun and without this energy, energy would not be transferred through out the pyramid, ecosystem and food web.

Producers get energy through photosynthesis and without producers getting energy from the sun and without this energy, energy would not be transferred through out the pyramid, ecosystem and food web.

Food chains and food webs

Food chains and food webs show the flow of energy through an ecosystem. Food chains are linear depictions of energy flow, while food webs show the multiple interactions among the different types of organisms. Food webs are generally more realistic portrayal of the energy flow in the system.

If you removed grass from my population then many organisms would die of and the energy pyramid and the flow of energy in my ecosystem would be very unstable

Trophic levels and energy pyramids  

The reason the producers have the largest section (base) is because it has the most energy and most organisms.

producers-1000 kg

primary consumers-100 kg

secondary consumer-10 kg

tertiary consumer-1 kg

The reason we use a pyramid is because it represents the amount of energy used/lost as the pyramid narrows, the farther you go up the less energy and organisms.

Photosynthesis

The reason the base/bottom of the pyramid is the largest is because it has the most energy/kcals and because their are lots of producers. And the reason the top of the pyramid is the smallest is because it has the least amount of energy and organism.

Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.

The role of decomposers  

Adaptations in grasslands: deep roots help plants survive prairie fires, animals hibernate when it becomes cold.

Tropism

Thigmotropism is plant response to touch. The most common example is the curling response of vines when in contact with an anything, elongation of cells on one side of the stem cause bending of the stem in the opposite direction.

Phototropism is the response in plants to unidirectional light coming from one source, such as a lamp or beam of sunlight. Cells on the shaded side of the stem elongate more than the cells on the lit side, causing the stem to turn toward the light.

Fungi, mold, algae, earthworm, millipedes, bacteria.

If their wasn't any decomposers in my ecosystem bacteria, nats, fungus, and any other harmful disease would spread.

Adaptations

Thigmotropism. By the plant closing up when touched helps the plant be shielded from preditors.

The reason plants and animals have adaptation is because they need the certain adaptations to survive in the environment.

Adaptations in grasslands:

Some plants can produce secretions or oils, like the poison ivy plant, if you pull it out of the ground it may cause sever itchy rashes.

The stick bug has adapted to camouflaging in to twigs and small tree branches in the grasslands.

Birds have adapted thicker feathers to withstand the bitter cold of the grasslands.

If you took the birds out of the grasslands and put them into the tundra they would have adapt to the cold weather of the tundra by growing even thicker feathers and gain fat.

Natural selection

Pulling this poison ivy and you get a irritating rash

Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment.

An organism in my ecosystem that has been naturally selected is a snake. The grass snake in my ecosystem has thin scales, but over time the snake has been naturally selected by making thicker scales to withstand the thorns and tough sharp grasses. Becaose of this natural selection the grass snake population has increased due to snakes not bleeding out due to getting cut on sharp thorns or grases an example of these grasses would be tall spear grass, native spear grass, elephant grass.

Good job

Go back and look at the instructions and my example for formatting. You are missing a couple of things. Also, see if you can find a more clear picture up top...yours is kinda blurry. I like the series of pictures at the bottom, but you need to separate them into biotic and abiotic.
