90 percent loss of energy gets lost at each step in a food chain, and when any consumer has to eat far more food than it ultimately stores as body tissue. If the food contains some material which is not metabolized and cannot be excreted (usually fat soluble rather than water soluble) that material will accumulate in the consumer's body. A carnivore eating the first consumer will receive a high dose of the material, which it, in turn will retain and pass on to the next level if eaten.
Second level carnivores are more likely to be affected by an insecticide than first level carnivores because they get the insecticide of the animal they ate and the one before. Third level consumers would be even more effected.
In general, there tend to be more herbivores than carnivores in an ecosystem. This is because herbivores form the base of the food chain, supporting the larger number of carnivores that rely on them for food.
Plants produce food Herbivores eat plants Carnivores eat herbivores Thus to keep everyone fed there have to be more plants than there are herbivores to eat them (or the herbivores would starve) and more herbivores than carnivores (or the carnivores would starve).
It is the way nature plays out. The carnivores eat the herbivores, so it is impossible to have more carnivores then herbivores. If there are too few herbivores around, the carnivores begin to starve, so for that reason there will always be more herbivores then carnivores. Most carnivores protect there territories from other carnivores, killing them if necessary, because they instinctively know an area can only support so many carnivores based on food supply -- which for them are herbivores. Also many carnivores are capable of practicing birth control to some degree to keep their numbers appropriate for the number of herbivores that can sustain them.
Yes, Sharks, Dolphins, and several other carnivores live underwater
A mother and a father carnivore produces more carnivores
I think there is a pretty even amount of carnivores and herbivores. There might be a bit more herbivores because they need more of their species to survive, since the carnivores hunt them.
carnivores. or more specifically cheetahs are carnivores
Second level carnivores are more likely to be affected by an insecticide than first level carnivores because they get the insecticide of the animal they ate and the one before. Third level consumers would be even more effected.
more poo!

no. There were more herbivores than carnivores and u think all dinosaurs are carnivores! =(

all of the prey would have to increase then more carnivores would be able to eat
well, men are more affected physically, women are more affected emotionally, if that's what you mean.. Wait, affected by what?
I actually think differently, or that there is at least another answer. Keep in mind that the 2nd level carnivores eat the 1st level carnivores, where the 1st level carnivores may eat insects or plants. I think its a matter of adaptation. Those 1st level carnivores are, of course, adopted to eating insects (their prey) and being sprayed with an insecticide.... so it does not really affect them, 1st level carnivores. Yet, The 2nd level carnivores are not adopted to eat the insects, unlike the 1st level carnivores. That said, when the 2nd level carnivores are eating the 1st level carnivores, they are also undertaking/eating the insecticide that is found in the 1st level carnivore's digestive system. P.S. Its only when you eat the particular insect, that you get insecticide. The particular insect cannot just leave poison on a plant, or "infect a plant."
