Answer:
1) Organisms in this level are either unicellular or colonial (Cellular level).
2) Organisms that live in a group called a colony (Colonial).
3) The work being divided up into specialized tasks (Division of labor).
4) A very long, contracting cell (Fiber).
5) A group of tissues working together as a unit (Organ).
6) A degree of organism complexity. Organisms at this level have their cells arranged into organs (Organ level).
7) The highest level of complexity of a living thing (Organism level).
8) The limiting of the function of a cell to a specific function muscle (Specialization).
9) A group of organs working together for a common purpose (System).
10) Organisms at this level have their cells arranged into systems (System level).
11) Cells working together to perform a particular task division of labor (Tissue).
12) Organisms at this level have their cells arranged into tissues (Tissue level).
Answer:
rise over run
Explanation:
rise refers to the number of units going u or down a graph
run refers to the number of units going left or right
it is seen as so; 
, 
, or 
Don't panic when I included "delta". Delta, it refers/means the small mathematical triangle found beside the rise and run symbols of y and x
1. The energy left in the Quaternary consumer level is 0.06283 kcal.
2. 0.65 units of energy is still available at the tertiary consumer level.
<u>Explanation:</u>
Energy flow in an ecosystem obeys the ten percentage law According to which ten percentage of energy from a trophic level gets transferred to the next trophic level. In the given question plants belong to the trophic level , producers and it transfers 10 percentage of its energy to the primary consumer level.
In the question 1 the energy that the producers have is 628.3 kcal. Ten percentage of this i.e 62.83 kcal gets transferred to the primary consumer level. Ten percent of that which is 6.283 kcal gets transferred to the secondary consumer level. Ten percent of 6.283 kcal i.e 0.6283 kcal energy is transferred to the tertiary consumer level.
Thus the Quaternary consumer level gets ten percentage of 0.6283 kcal i.e 0.06283 kcal. In question B the initial energy at the primary level is 650 units. Ten percentage of 650 i.e 65 units reach the primary consumer level. Ten percentage of this 65 units then reaches the secondary consumer level. Thus the secondary consumer level has ten percent of 65 i.e 6.5 units of energy.
So the energy that reaches the tertiary consumer level is ten percentage of 6.5 i.e 0.65 units.
