Why are species critical to the survival of an ecosystem?
Plants: They are needed to produce oxgen, and feed the herbavores. Prey: They feed on plants, and feed the predators. Predators: To eat the prey, and get eaten by greator predators You see, everything is needed to have a stable ecosystem. Now you must put into consideration, that if a lower part of the chain is smaller than the larger part, then the ecosystem would fail. You need more plants than herbavores, you need more prey for predators. It is a large cycle.
Why are there more insects on crop plants than wild plants?
Crop plants are more susceptible to insects
Why are there more plants in the tropics than in the desert?
There is much more rainfall in the tropics than in the desert which supports a greater number and variety of plants.
Why predators play an important role in any ecosystem?
Here is a simple but concise answer to your complex question. Ecosystems require carnivores for balance. Without carnivores, plants are are devastated by a surplus of herbivores, and thus cannot survive. This in turn threatens the herbivores with starvation, which is a much more painful death than being preyed upon by carnivores. Essentially, carnivores prevent plants from being wiped out by excessive herbivores, and save said herbivores from starving. By eating them. Sounds harsh, but the alternative is ecological collapse.
Do Non-flowering plants have more leaves than flowering plants?
on average, yes.

Do yak's have predators?
Yes. They're a prey animal, which makes them more than inclined to have predators.
Why are there more insects on crop plants than wild plants?
Crop plants are more susceptible to insects
Why do adult plants have more roots than young plants?
Because adult plants requirement for water and minerals is more than a young plant.
Why are large predators more common in savanna grassland than in deserts?
Savannas have grass that attracts herbivores that are the prey of predators.
Do predators use more or less energy than producers?
LESS
What tropical rainforest animals eat plants and meat?
In a stable ecosystem (like a rain forest), there will usually be fewer predators/meat eaters than prey/plant eaters, because the higher up you are on the food chain, the fewer of you there will be; If there were fewer prey animals than predators, they would all be eaten quickly, and the predators would starve and the ecosystem would break down. But if there are more prey animals than predators, the prey animals will live long enough to reproduce and keep the population stable, the predators will still have food and the ecosystem will stabilize.
Why are there fewer vacuoles in plants than in animals?
more cells in plants.
Do large predators use more or less energy than producers?
LESS
Is it possible for the top level to be wider than the level before it?
no, it is impossible for there to be more predators than there is prey
Why are there more plants in the tropics than in the desert?
There is much more rainfall in the tropics than in the desert which supports a greater number and variety of plants.
Why do you think there are more plants growing in the mountain than in the desert?
Generally, the mountains receive more precipitation than does a desert so more plants are able to grow there.
