Arlecino [84]

An organism  is defined as a living thing which can function  on its own. It has interdependent parts and is capable to some degree of responding to stimuli, can reproduce, grow and develop and maintain homeostasis. Plants are organisms because they fulfill all these characteristics.

Evolution is likely to occur because of I. the potential for a species' population to increase. II. genetic differences in offsp
malfutka [58]
Lll. a limited supply of necessary resources. If there isn't enough resources the species will have to learn to adapt to be able to gather the new food supply they need. Such as birds and there beaks, if the insects population went down and that was the main food supply for that type of bird they would have to be able to adapt in order to survive, so evolution occurs. Over time that bird would change to adapt to its new feeding source.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Reika [66]

Answer:

I think yes, humans are an invasive species.

Explantation:

        I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.

I hope this helps. :)
