- 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.
lets say there are 20 gazelles in a group,and a drought comes through and there are alot less greens for the group.The number drops to 15.then the drought ends and they start to reproduce and the number rises to 19.they go and thrive for a long time and the number rises to 24......then the group gets lost and has no shelter,then they get attacked by a group of lions and the number drops again. Just depends on how much they have of the things they need.
- In biology, common limiting factor resources or environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.
in my ecosystem there are many carnivores and many herbavores. If things start to change and say they have a drought and then the greens that the gazelles eat will dissapear, then the gazelles will start to die of hunger,then say the lions wont have anything to eat,and so on and so forth. Its sort of like cause and effect.
producer(s)- Producers in the savannah include trees, shrubs, and grasses. The sun provides plants with the energy to grow.
primary consumer(s)- are herbivores, such as giraffes and zebras, they consume the vegetation.
secondary consumer(s)- are carnivores that include inhabitants that feed on herbavores, such as cheetahs and lions.
tertiary consumer(s)-are organisms that consume secondary consumers.
scavengers are animals that eat leftover meat (dead or alive) an example is a hyena
decomposers are things like bacteria that break down dead animals.
food chains and food webs
in my ecosystem food webs are more effective because instead of showing energy flow from organism to the next its shows energy flow from more than one organism to the next.
if i removed one population from the food web then the whole web will be effected. If say the elephant went extinked then the lions and hyenas ect. would have less food and eventually will fight each other for food.
trophic levels and energy pyramid
the chemical equation is C6H12O6
C stands for Carbon dioxide
H stands for hydrogen
O stands for oxygen
the elements needed are water,oxygen,carbon,and sunlight and together they make glucose.
phtosynthesis takes place in an organelle called chloroplast,and it changes light energy to chemical energy
tropisim is the way an organism moves in responce to something.
the Umbrella Thorn Acacia is an example of geotropism because the roots grow down into the earth in the affect of gravity.
it helps them adapt to the enviroment around them. maybe to find ways to water or to avoid obsticals under ground near the roots.
role of decomposers
without decomposers there would be little nutience in the soil for plants and many would start dying.plants will make less food for themself that means less energy to the consumer,and then may even end up dying compleatly
some decomposers found in the savanna are earthworms and fingi
the importance of having adaptations is if you did not adapt to your enviroment you would not be able to live long there.They help them survive like if your a plant and your in the desert you need to find a way to store water and a way to withstand the heat and the intense sunlight,or you wont be able to survive.
The trees and plants have longer roots so that they have the ability to extract water from deeper into the ground.They have fewer leaves so that less moisture is lost though the process of evaporation, the leaves are also very small and thorny to reduce moisture lose.The trees lose their leaves during the dry season to keep and conserve more moisture.
ANIMAL ADAPTATION through various ways,like migrating(moving to another area) and hibernating until the season is over. Grazing animals, like gazelles and zebras,feed on grasses and often use camouflage to protect themselves from predators when they are roaming in the open. Some animals, such small mammals and rodents, use camouflage to blend in with their surroundings and have grass- colored tan fur. These small animals also avoid preditors burrowing underground and by being nocturnal (active during nighttime). http://www.education.com/science-fair/article/sava...
well it would not be able to adapt very quickly and it will try to adapt and end up not surviving
- the process where organisms better adapted to their environment tend to survive and produce more offspring.its important because if they cant adapt they wont be able to produce offspring and will end up extinct.
a lioness is a good example of natural selection because of how the color of the fur blends with the color of the grass.over time the fur of the lion/lioness changed so they could blend in with the grass to hunt.Thats why you see some lions with lighter fur or darker fur.
