Energy! Because plants take in sunlight, their energy is stored as glucose you eat, and they gets converted to energy!
the one that is the thing
Since each plant or animal in a food chain is dependent on the plant or animal below it for food if one of those in the chain goes away (becomes extinct) or just isn't available in enough quantity, the next one up the chain starves to death.
One thing dying or becoming extinct
Every living thing is part of one food chain or another. A lion is the top predator in its food chain, and in the African savanna food web, it is at the same level as hunting dogs, leopards, cheetahs, and hyenas
Energy passes from one living thing to another through a food chain or food web. Producers, such as plants, convert sunlight into energy through photosynthesis. This energy is then consumed by herbivores, which are in turn consumed by carnivores or omnivores.
One example of a good thing is a health snack. A Example of a bad thing to eat for a athlete is greasy food. Another bad thing is chocolate food.
food chain
It really depends on which lake you are talking about. It normally goes algae, small fish, maybe a water snake, alligator turtle, to a hawk. That's just one variation though. There are thousands of combinations you can make, but a food web really brings all of the possibilities together.
The transfer of energy from one living thing to another is known as a food chain. In a food chain, energy moves from producers (plants) to consumers (animals) as they eat each other. This process demonstrates the flow of energy through an ecosystem.
Generally it's the same thing. Technically albeit the food web is a sort of graph that shows where energy is delivered through animals. (for example energy from phytoplankton go to clams which then goes to seagulls.) While a food chain shows in what order each animal is on a chart depending on how many predators they have. (for example mice have many predators and will be at the bottom of the food chain, while lions have few predators and are at the top of the food chain.)
A food chain is a series of organisms where each one is eaten by the next in line. It shows how energy and nutrients are passed from one living thing to another in an ecosystem. For example, grass is eaten by a grasshopper, which is then eaten by a frog, forming a simple food chain.
Food chains are the transfer of energy from one living thing to the next up in the food chain but energy can be transferred in a living thing through: Movement Respiration Sensitivity(senses: sight, smell, etc.) Growth Reproduction Excretion Nutrition
