In an ecosystem bacteria are considered? A. Primary Consumers B. Secondary Consumers C. Decomposers D. None of the Above
Bacteria are considered decomposers within the ecosystem because, bacteria helps with breaking down of dead plants and animals. When trying to understand this question you want to think about what a decomposer means. To decompose means to break down. When I think of bacteria in the environment I think about how it can make you sick (aka break you down). When connecting those two thoughts I am able to comprehend why bacteria is considered a decomposer.
What are the reactants and products of photosynthesis?
The reactants involved in photosynthesis are carbon dioxide, water, and sunlight. The products of photosynthesis are glucose and oxygen. Fun Fact: if you flip the reactants and the products you get the equation for cellular respiration. The way I remember the reactants for photosynthesis is by thinking what does a plant need to survive. First I know the plant needs water and sunlight. I know this from my childhood. By obtaining this knowledge I know that water and sunlight have to be two of them. When I am trying to remember the third I think of what do I breathe out of my body which is carbon dioxide. To remember the products I think about what plants give us. They give us food and oxygen. That is how I remember the products.
Sodium that is absorbed through the small intestine is driven by what type of transport?
This would be active transport. It is active transport because the sodium molecules are absorbed across a cell membrane into a higher concentration area. A way to remember this would be by thinking of what the word "active" means. When you think of being active you think of work being done. So now with that being said you would think of the sodium particles having to do work to get across the small intestine membrane. That is how you remember it is active transport.
