carrying capacity is the limit of how many individual organisms an ecosystem can support for example bision poulation is changing because the land of the prarie is geting smaller that means less food less shelter
Limiting factors and predator/pray relationship
Limiting factors are factors that influence carrying capacity a predator pray relationship is a prairie chicken and the prairie falcon it is affected by limiting factors because the prairie habitact is getting smaller so it hard for the chickens to hide and the population is getting smaller year.
Energy roles are deteirmined by how an orginism gains energy and how it interacts with other living things in its ecosystem.
The producers make their energy own energy The consumers eat other organisms. The decomposers eat dead organisms then the nutrients returns back to the ground and the pyramid starts over.
Producers get their energy from the Sun but the reason why they are the most important in the energy pyramid is because they start the whole pyramid without them other organisms will not have the energy to transfer to other organisms.
I think food webs are more realistic then food chains because a food web has more animals so it can show how it work in an ecosystem.
If one population is taken away it destroys the ecosystem it would make one population to increase and another to decrease.
Trophic levels and energy pyramids
The reason why we use pyramids for energy transformation is because the energy gets smaller and smaller a pyramid shows that.
Producers are the biggest leavle because it has the most energy and 3rd levale consumers have the least amount of energy .
Tropism is turning or bending movement of an organism towards or away an external stimulus. Two examples of tropisms is a Sun flowers follow the sun that is an example of phototropis and some vines wrap around trees that is an example of thingmotropism.
The reason why tropisms are so important to plants is because it helps the plant get its nutrients for example if a sun flower did not follow the sun it would not do photosynthesis and die.
The role of decomposers
Decomposers are important to the environment because they are the ones that help turn waste into soil so the producers can grow and the food web (chain) can start over.
Adaptations are in important to and animal because it help them survive and reproduce in its environment for example a bird needs hooked talons so it can grab fish and if a tigerhad to eat meat it would have to have sharp teeth.
Adaptations -Webbed feet -Sharp Teeth -Fur -Claws
If adaptations were in the wrong place they would be in no use and they would lack ability to survive and reproduce.
Natural selection \ Natural selection is traits becoming either more or less common in the population, but if we did not have it newborns will not have the traits to survive in their ecosystem .
Certain types of Mustard seed plants have natural selected in the prairie when a caterpillar chew it the plant feels its vibration and releases a chemical that makes the plant taste bad to herbivore . It changes how herbivores eat plants they watch out for the plant.
