The muddiest point for me is how to define a biome. Also another thing that I don't fully understand is the energy transfer among the organisms and how to distinguish on a food web which animals are 3rd order and 4th order consumers or 5th and 6th consumers. It would be great if someone could explain this to me!
Thanks and Have a great day!
I would define a biome as a group of ecosystems, or an environment with similar biotic and abiotic factors, that share similar climates. Examples can be the desert, tundra, etc.
ReplyDeleteA biome is a region that has a specific climate (temp and precipitation)... because of that, biomes tend to have characteristic plant and animal life.
ReplyDeleteExamples of biomes are tundra, desert, and taiga.
For food webs, the most imporatnat thing is to follow separate food chains. The primary consumer is always the animal (or other heterotroph) that eats a producer. Primary means first. So you just count from there!
