Which organism is a secondary consumer (3rd trophic level)? a. larvae b. copepods c. killifish d. snapper
anygoal [31]

ANSWER:  B, killifish

REASONING: A secondary consumer consumes animals that eat only plants.  Larvae and copepods do not fit these descriptions, because they do not eat animals.  Snapper do eat animals, so do not fit the description either.  Killifish eat small animals that do eat plants.

The minimum amount of energy needed to start a chemical reaction is known as:
nadya68 [22]

Answer:

The correct option is B. Activation energy

Explanation:

The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.

For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.

The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
