Answer:
The circle of life, in which energy flows into the world from the sun, giving plants that energy to live. All of the organisms in an ecosystem are chemical machines driven by the energy captured in photosynthesis. The organisms that first capture energy, the producers, include plants, some kinds of bacteria, and algae. All other organisms in an ecosystem are consumers.
The plants energy will then be transferred to a small animal, most likely a rabbit or maybe a mouse; depending on the plant. The small animal will then be eaten by a bigger more dominating animal like an eagle or a snake. It just goes on and on. The eagle or the snake will get eaten by a bigger animal or will decompose into the earth giving the soil and plants around it that same energy.

Answer:
The correct answer is "5-1-3-2-4".
Explanation:
Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:
5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.
1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.
3) Several endocytotic vesicles fuse to form an endosome.
2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.
4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.
