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.

Answer:
Option C, At a subduction zone, oceanic crust is forced deep into the Earth.
Explanation:
At sub-duction zone, the dense oceanic plates coincides with the less dense continental plates and thus sink below the continental plates. Sometimes these oceanic plates being dense, sink to greater depth with in the earth’s mantle. The sub-duction zone causes earth quakes of high intensity when oceanic crust penetrates to greater depths of earth crust as they tend to change the rheology of the earths’ mantle and also causes bending of plates
Hence, option C is correct
I only know 4 which is hotter
Answer:
(For USATestprep) C. The rate of photosynthesis increases with an increase in carbon dioxide.
Explanation:
Carbon dioxide is one of the reactants in the process of photosynthesis. The rate of photosynthesis increases with an increase in carbon dioxide.. If carbon dioxide is limited, then photosynthesis would slow down.
