The missing term is "phytoplankton." Phytoplankton are microscopic organisms that form the base of the marine food chain by converting sunlight into energy through photosynthesis.
If an animal from a food chain disappears, it can have a cascading effect on the entire ecosystem. This can disrupt the predator-prey balance, leading to an increase or decrease in certain species populations. It can also impact the availability of resources for other animals in the food chain, potentially causing a chain reaction of consequences throughout the ecosystem.
the one below it will die because it will have nothing to keep its population down and then it will eat up all its food so it and its food dies and then humans will because the world has ran out of food.
