well of course first all the animals will become endangered . Then one species at a time all the animals will die off of hunger.
the animal population increases
The entire population will die out and then moles will take over the world.
Y
The concentration of carbon dioxide decrease.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
The mouse population will increase. (apex)
In population biology, carrying capacity is defined as the environment's maximal load which is different from the concept of population equilibrium.Hence, if an ecosystem decreases in space, competition will also decrease.
Assuming the temperature stays constant and there is no leakage of gas, then if the container decreases in size then the pressure will increase.
shrimp will have more difficulty finding food
The animals will extinct. If there is a hole in ozone layer.
Assuming the seal population in question routinely feeds on the salmon, if there are less seals, more salmons will live and so their numbers will increase.
the species's population would increase but depending on the animal, a population rise could begin to affect other animals
Generally, if the population of a species is larger than the area can support, animals migrate to other locations, die of starvation, disease etc. until the population decreases to a sustainable level. Unfortunately, if the over population problem depletes the environment enough the sustainable level drop from what it was before the over population problem occurred.
