What proportion of energy is transferred from one trophic level to the next in an ecosystem

Biology
2 answers:
laiz [17]3 years ago
7 0

Answer:

10% of energy

Explanation:

Within an ecosystem, there occurs a transformation of energy from one trophic to the next. This leads to the transfer of energy from the primary producers to the consumers as well as the decomposers. Looking at the earth's ecological pyramid, out of the total energy, only 10% of the energy is transported to the next trophic level, and the remaining 90% is lost as heat energy. This forms a chain. where the organisms are depending on each other.

Answer:

10 % energy of one trophic level is carried to the next trophic level.

Explanation:

Organisms at each trophic level consume some of their available energy for respiration and maintenance. Therefore, 10% energy from the organisms of one trophic level is available for the organism of the next trophic level. This is also called as 10% law of energy transfer and determines the energy efficiency of food chains in the ecosystem. For example, if grasses in a food chain have 100 calories, only 10 calories are available for a herbivore such as a deer.

sergey [27]

Answer:

exposed ovules

Explanation:

Gymnosperms are a type of flowerless plant that tend to produce cones and seeds. This is why the name refers to "naked seed", seeing since the gymnosperm seeds are not positioned within an ovary. Therefore the presence of exposed ovules or the structure that contains the seeds in a place would immediately indicate that this is, in fact, a gymnosperm.

Name 3 critical areas of the body that are accurately maintained by homeostasis.
tester [92]

Answer: Respiratory system, Excretory system, and Endocrine system.

Explanation:

Homeostasis is the process through which several organ systems work to maintain a stable internal environment in the body. There are three organs of the body which ar eaccurately maintained by homeostasis:

Respiratory system: High carbon dioxide content in the blood triggers faster breathing. Most frequently, the lungs exhale, which quicker extracts carbon dioxide from the body.  

Endocrine system: High blood sugar content causes insulin release by an endocrine gland called pancreas. Insulin is a hormone which helps the cells absorb blood sugar.

Excretory system: A low blood level of water causes kidney accumulation of water. The kidneys contain more concentrated urine, so less water from the body is lost.  

Hence, three critical areas are respiratory system, excretory system, and endocrine system that are accurately maintained by homeostasis.
