It has to be A i hope this helped
Answer:
Part A
The green plant is a producer
The grasshopper is a herbivore
The Rat is a Omnivore
The snake is a Carnivore
The eagle is a Carnivore
The mushroom is a Decomposer
Part B
The arrow between each organism indicates the direction of energy flow which shows the direction in which the energy transfer takes place from one organism to the next, with the general source of energy for all animals being the Sun.
Part C
A sample food chain can be presented as follows;
Sun, Green plants → worms → Frogs → Snakes → Coyotes → Bears → Tigers → Mushroom → Plants
Explanation:
Heating the reaction flask on a hot plate is an example of supplying activation energy to begin a reaction.
Explanation:
<u>Definition:</u>
Activation energy is defined as the minimum amount of energy required to start a particular chemical reaction.
For example: When hydrogen and oxygen are mixed together it does not immediately start the reaction to form water. So, to start the reaction a small electric spark is provided or it is heated to provide some energy. This energy causes the molecules of hydrogen and water to react, thus producing even more molecules to react and finally water is formed.
Here the electric spark or the heat provided is the activation energy.
Answer:
Most substituted alkene is produced as a major product
Explanation:
- Dehydration of 3-methyl-2-butanol proceeds through E1 mechanism to form alkenes.
- Most substituted alkene is produced as major product because of presence of highest number of hyperconjugative hydrogen atoms corresponding to the produced double bond (Saytzeff product).
- Here, a H-shift also occurs in one of the intermediate step during dehydration to produce more stable tertiary carbocation.
- Reaction mechanism has been shown below.
Because many animals are likely to die from contamination
