[Q]: An island in the Pacific ocean has a strange an compact ecosystem. There are only 4 species of living organism on it. There are plants, Insects, birds, cats. Because of this there is a very specific food chain on this island. Any new species added to it has cause the population of all other species to decrease. This is because when a new species is added it causes the others to not have enough food as they all feed on each other. The insects eat the plants, the birds eat the insects and the cats eat the birds. When a species of wolf that eats the cats was added the plants began to die off because the wolves outlived the cats so the plants could not get the energy in time to regrow before the insects would eat them. Because of this the insects would die, then the birds then the cats. because the energy source for each species was being consumed faster than it could be produced. Will the insect population decreasing cause the available energy to the bird population to increase or decrease?
****
[A]: decrease
