Answer:
First off, we need to establish what secondary consumers are. Primary consumers are all herbivores; they eat the producers. The secondary consumers are on the next trophic level up; they eat the primary consumers. They thus help to control the level/number of primary consumers; otherwise, the number of primary consumers would grow too high, and the producers would all be WIPED OUT.
Now, you may be wondering what controls the amount of secondary consumers? The answer is tertiary consumers. What controls the tertiary consumers? At this point, energy does the job of limiting the population. As you move up trophic levels in an ecosystem, the amount of energy in each trophic level goes down by 90%. So like if you started w/ 1000000 joules of energy in the producer level, that would be 100000 in the primary, 10000 in the secondary, and only 1000 in the tertiary.
Answer:
The correct option is b. 0.453
Explanation:
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
<u>Note</u>:
• <em>Observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals
</em>
<em>• Expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.
</em>
CC= (7/1000)/0.16x0.08
CC= 0.007/0.0128
CC=0.5468
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.5468
I = 0.4531
Answer:
C.) castings
Explanation:
Worm castings are a biologically active mixture of bacteria, enzymes, plant materials and animal dung leftovers, as well as earthworm cocoons. When worms digest food or other materials, complex nutrients are broken down into more accessible forms than those present in the castings. I hope this helps! ^-^
If you have too much CO2 in your blood, you will hyperventilate (or breath faster) to get rid of the CO2 and get more oxygen
