Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.
(look, im not good at gammar, so you should get this looked at before entering it. I put it through gammarly if that helps.
Peptide bonds connect amino acids.
Please correct me if I'm wrong!!! I'd be happy to fix it!! :)
Variation of trainers HELP species.
An energy pyramid is always related to the organisms food web. A increase in no of tropic levels could make it complex. Also the reason for only 4 or 5 is to make it simple to understand.
<span>B. RW. Whenever something is dominant the letter will always be capitalized on a punnet square. Since both given animals are homozygous dominant then the answer should all be in capital letters. Since there are no recessive parents which is represented by lowercase letters.</span>
