Answer:
D. About ten percent of the energy at one trophic level is passed to the next trophic level
Explanation:
In an ecosystem, the amount of energy decreases at each trophic level. Precisely, <u>the energy transfer from lower trophic level ot high trophic level is calculate to be 10% of the previous level</u>. Rest of the energy is just wasted through metabolic activities (e.g. heat). For example, if a grassland ecosystem has total energy of 10,000 Kcal, only 1000 Kcal would be transferred to the primary consumers, and then 100 Kcal to secondary consumers, and finally 10 Kcal to tertiary consumers. See figure for better understanding.
First option is incorrect because energy flow in an ecosystem is unidirectional. Option B and C are incorrect because energy flow is not dependent on specific animal/plant species but rather at trophic levels.
Answer:
Option C, Aneuploidy
Explanation:
Aneuploidy is defined as the condition when offspring/daughter cell has abnormal number of chromosomes.
In the process of nondisjunction, the pair of homologous chromosomes do not separate and hence the sister chromatids fails to separate.
Hence, option C is correct
Answer:
Explanation:
Dissolving is importan because its a whole life sicle.
this is how desolving works:
1.an animal dies and starts desolving
2. when the animal desolves its fertilizes the ground and then grass grows
3. another animal comes and eats the grass
4. when that animal dies or gets killed by a predator it starts desolving
And then the 4 sicles repeat over and over.
They survive without water by entering a special mode, otherwise called as shriveling. They can lose even 95% of water in their body and still live, even though they would look like dead plants, they would actually be alive. In the absence of water, tardigrades use a sugar called trehalose, which becomes their source of life until they find some water.
