The true statement for the energy in ecosystems is "Producers only absorb 40% of the sun’s energy, most of which is lost during photosynthesis". The correct option is A.

<h3>What is ecosystem?</h3>

An ecosystem is a geographical area in which plants, animals, and other organisms, as well as weather and landscape, coexist to form a life bubble.

Ecosystems contain both biotic and abiotic components. Plants, animals, and other organisms are examples of biotic factors.

Energy must be transmitted throughout an ecosystem. The sun is the ultimate source of energy in an ecosystem.

Plants and marine ecosystems make up the majority of the terrestrial ecosystem.

Thus, the correct option is A.

Which of the statements about half-life are true?
Oksana_A [137]

The statements which are true about half-life are given below:

  • A radioactive element's half-life stays the same when its temperature changes.
  • A radioactive element's half-life stays the same when the pressure upon it changes.

Thus, the correct options are B and F.

<h3>What is Half-life?</h3>

The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.

The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.

Therefore, it is well described above.

An organism is discovered that thrives both in the presence and absence of oxygen in the air. Curiously, the consumption of suga
Vinvika [58]

A facultative anaerobe.

Explanation:

Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.

Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.

Aerobic respiration produces 32 molecules of ATP from one  molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.

Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.
