An example might be different shaped beaks to gather different types of food. It must be something that helps an organisms survive.

Put the following food chain into an energy pyramid.
Oak tree > squirrel > snake > mongoose > mushroom
Oak tee it in the bottom level. Squirrel is in the second level. Snake is in the 3rd level. Mongoose is in the top level.
Mushrooms (decomposers) not in pyramid.

Name 4 abiotic parts of the ecosystem.
Rocks, sun, temperature, water, soil, air.

How can a food chain be disrupted and what happens?
An organism is taken out and affects all the others through starvation or over population.
500
What is the difference between commensalism and mutualism?
In mutualism BOTH organisms are helped. In commensalism one organism is helped and one is unaffected.
