Lack of suitable food !
It was the gekoes that killed them because of the DDT
Geckos are not at the top of the food chain. They are at the bottom.
If a component is left out of the food chain then something will not be able to eat it. Then it will die, and the component above it in the food chain will not be able to eat it, and will die. Basically, if a component is left out of the food chain, the food chain collapses.
The food chain would disrupt. Mouse-eating cats will die, Cat-eating dogs will die, and so on.
If you are at the top of the food chain, if you prey is poisoned or ill, you can die from illness.
They die
they die all the time
If an animal dies, it affects your food chain; because more animals will die and in the end all the food will run out for predators if they eat to much prey. If you are human it will also affect your food chain because you need meat in your diet.
carabaos are buffaloes. so they help in the food chain. only if they die, there will be an adverse effect on the food chain.
We All Die
shut up die stupied
If the produce is removed then the food chain will cease to exist. The consumers will then have nothing to eat and so will die.
