The endoplasmic reticulum is the term which describes an extensive network of tubes, sacs, and vesicles throughout a cell that provides transport as its main function. The endoplasmic reticulum is a small organelle and is found in most Eukaryotic cells. It is not found in red blood cells. The endoplasmic reticulum is a network in the core of the cell and occurs within the nuclear membrane and is involved in the synthesis of lipids and proteins. The endoplasmic reticulum also usually has ribosomes attached to it.

Explanation:
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm, energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move. Don't confuse respiration with breathing. Respiration releases energy, while breathing
Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.
It's B, Most them can make or produce their own food.
