Are sharks part of the food chain?
As apex predators, sharks play an important role in the ecosystem by maintaining the species below them in the food chain and serving as an indicator for ocean health. … By taking sharks out of the coral reef ecosystem, the larger predatory fish, such as groupers, increase in abundance and feed on the herbivores.

follows one path of energy and materials between species
. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. … Producers are autotrophs, meaning they produce their own food through photosynthesis or chemosynthesis.
Can sharks smell period blood?
