1. <span> A. The algae directly feeds the large-mouth bass and wood duck. Consumers are the same thing as heterotrophs.
2. </span><span>The blue arrow points to an animal which gets all its energy from (i.e., eats) only other animals
3. </span><span>Primary consumers are the organisms which eat producers. So without the primary consumers eating the producers, the number of producers will probably increase.</span>
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
If you hit your head hard possibly. if just playing and running no.
D. Proteins are composed of amino acids and determines all the structures and functions of the organism.
