Sediimentary rock is formed when sediment is deposited out of air, ice, wind, gravity or even water. I Doubt it would remain a sedimentary rock so the best answer would be metamorphic rock.

List four ways in which members of the same species can cooperate with each other.
ArbitrLikvidat [17]
Cooperation is common in non-human animals. Besides cooperation with an immediate benefit for both actors, this behavior appears to occur mostly between relatives.[1] Spending time and resources assisting a related individual may at first seem destructive to the organism’s chances of survival but is actually beneficial over the long-term. Since relatives share part of their genetic make-up, enhancing each other’s chances of survival may actually increase the likelihood that the helper’s genetic traits will be passed on to future generations.[6] The cooperative pulling paradigm is an experimental design used to assess if and under which conditions animals cooperate. It involves two or more animals pulling rewards towards themselves via an apparatus they can not successfully operate alone.[7]

Explanation:

All living organisms such as fish,plants and animals  need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.
