Answer:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.

Answer:
active transport, like Na + ions leaving the cell
Explanation:
The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.
Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.
The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.
The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.
