Answer:
carbon dioxide is correct
The chemical bonds which hold the molecules of ATP together are high energy bond, that means that, they possess a large amount of energy. When these bonds are broken energy is always release to perform work inside the cell. At the same time, reaction coupling also occur anytime an ATP molecule is broken down. Reaction coupling involves linking the hydrolyisis of ATP molecule, which is energetically favorable with another chemical reaction, which is energetically unfavourable. Thus a product of one reaction is picked up and use as a reactant in the second reaction.
Accessory pigments absorb energy that chlorophyll does not.
It should be a hypothesis
False in order for an ecosystem to survive there has to be some sort of competition. for example, if there were no sharks to eat little fish the little fish would over populate and then the little fish would run out of food which then means that whatever the little fish ate is now extinct and so on hinting the food chain's name. If it wasn't for competition nothing would survive
