Food Chain is the chain in the Food Web.
A limiting factor causes a population to decrease in size. A few limiting factors are food, shelter, water, space.
Dependent limiting factors include: competition predation parasitism disease
Independent limiting factors include: unusual weather natural disasters seasonal cycles certain human activities-such as damming rivers and clear-cutting forests
Level 1: Plants and algae make their own food and are called primary producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores which eat herbivores are called secondary consumers. Level 4: Carnivores which eat other carnivores are called tertiary consumers. Level 5: decomposers which have no predators are at the top of the food chain
Factors are things that affect an organism. Biotic factor: Living organism (food) Abiotic: nonliving: (The five most important ones are: Oxygen, Shelter, Temperature, Soil, Water)
An autotroph is an organism that creates its own food through photosynthesis or chemosynthesis.
This is like a plant or protist. A heterotroph is like a human or other animal; they cannot produce their own food and must eat other organisms to live.
mutualism- both species benefit from the relationship. parasitism- one specie benefits while harming the other commensalism- where one benefits and the other is not harmed nor benefited.
Biological diversity means the diversity, or variety, of plants and animals and other living things in a particular area or region.
