So that the species does not become extinct.
so the animals can mate and have kids
So it can reproduce and its species can survive...
Fertilization is important so species can have genetic variation. It is also important so the species can pass on their genes.
so we can survive !!
We have to reproduce so our species can survive which is the main purpose.
Evolution adapts organisms via their dna and genes over periods of time for different circumstances. Survival of the fittest keeps the fittest members of a species alive to reproduce and pass on the genes that made them survive and over time the genes of the species will change to be able to survive better. So the ancestral species could go extinct so fish could into species intelligent enough to avoid nets and hook/lures and over time we won't be able to catch them and will need to move on.
It is important for species to avoid predators so they don't get eaten or hurt.
so we can have water and we need to survive and also eat fish
Members of a species are said to live in the habitat of that species.
Species can change is there is a mass extinction or if the type of species changed the type of climate or terrain which would would make the species evolve to its new environment so that it can survive.
Every animal is a part of the food chain, so mass extinction can have very bad consequences for the species that survive. The surviving species must learn to work around the animal that has recently become extinct.
So Judaism wouldn't die out.
