Explicación
## Step 1This question is about the basis for food chains in some caves, particularly those that lack sunlight. The options provided are sulfuric acid, bird nests, cockroaches, and bat droppings.## Step 2In the absence of sunlight, photosynthesis cannot occur, which means that plants cannot produce their own food. This disrupts the traditional food chain, which typically starts with plants.## Step 3In such environments, the primary producers are usually chemotrophs, which are organisms that obtain their energy by oxidizing inorganic substances, such as sulfuric acid.## Step 4However, in the context of caves, the primary producers are often chemolithotrophs, which are organisms that use inorganic substances as a source of carbon and energy.## Step 5In the case of caves, the primary producers are often chemolithotrophs, which use inorganic substances as a source of carbon and energy. These organisms are typically found in the form of bat droppings, which provide the necessary nutrients for other organisms in the food chain.
