Answer:
Organisms need energy because:-
To live
To repair and regenerate body cells
To grow
Hey there!
Answer: 400 k-cal
I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.
Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal
As we plug in this formula into our problem above, our answer would be explained below.
40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal
Answer: 400 k-cal
Blue whale, mushroom - heterotrophs
rosebush, algae, pine tree - autotrophs
the color of the light
photopigment are unstable pigments that undergo a chemical change when they absorb light
Answer:
1. Obtaining energy
2. responding to a stimulus
3. reproduction
4. excretion
Explanation:
1. All living organisms require energy for their life processes. This energy is derived from food. The food we eat contains biomolecules that store energy. The energy stored by these food molecules is released by a process called RESPIRATION. Image 1 shows a cat trying to obtain energy by feeding. The food will eventually be broken down to release energy.
2. Stimulus is any thing (whether internal or external) that causes a change in an organism. In image 2, a man is responding to a sudden change in his back, which is pain.
3. Reproduction is a characteristics of living organisms that involves the production of young ones. Image 3 depicts two cells undergoing fertilization (fusion of nuclei) to produce a new cell. In turn, the cell divides again to form two gametes. The cycle continues like that.
4. Excretion is the removal of waste products from a cell. According to Image 4, the cell allows a food particle in and releases the waste contents out of the cell.
