Because they are autorotrophs(they make their own food)so most organisms depend on them.
True
Because they break down what they are made of
This is the Prophase.
<span>1) The chromosomes coil up and become visible while the nuclear envelope disappears.
2) Sister chromatids are appears.
3) A centriole forms at each pole and spindle fibers made of microtubules grow out of it.
4) Short microtubules stick out from the centriole in a star shape known as an aster.
I don't remember liking biology but I do remember some things from it.</span>
Insects (Insecta) are the most diverse of all animal groups. There are more species of insects that there are species of all other animals combined. Their numbers are nothing less than remarkable, both in terms of how many individual insects, as well as many species of insects that are. In fact, there are many insects that is not very known how to count them all, the best thing we can do is to make calculations.
Approximate scientists who can be as many as 30 million species of insects alive today. To date, they have identified over 1 million. At any time, the number of live insects on our planet is amazingly, some scientists estimate that for every human being alive today, there are 200 million insects.
The success of insects as a group is also reflected in the diversity of habitats in which they live. Insects are more numerous in the land such as deserts, forests and grassland environments. They are also numerous fresh water such as ponds, lakes, streams and wetlands habitats. Insects are relatively scarce in habitats marine, but are more common in the waters brackish, like marshes and mangrove
Good luck!
