Answer:
The energy foundation in a deer cave ecosystem are the organic material, such as guano, other animal droppings and washed-in plants during flooding. Excess rainwater washes leaves, twigs and plants into a cave, providing munchies for insects and other animals.
Explanation:
The food chain in the cave start from the poop of bats known as guano, other animal droppings and washed-in plants that provide nutrients for fungus and microscopic bacteria. Then, millipedes and tiny crustaceans feed on the fungus, bacteria and the nutrients left behind. Bigger insects, such as cave beetles, feed on these millipedes, crustaceans and even the eggs of cave crickets. Centipedes, cave spiders, salamanders and cavefish feed on insects smaller than them. Some cave centipedes grow so large that they feed on bats.
