What happens to the energy released during cellular respiration?
The energy released during cellular respiration is used to synthesize ATP (adenosine triphosphate), which is the energy currency of the cell. ATP is then used to power metabolic processes such as protein synthesis, muscle contraction, and active transport.

In this ecosystem, oak trees have a biomass of 124,778 gm2 and create 78,871 kcalm2yr of energy.

It is not possible to determine how much energy the secondary consumer will have based on the information given. The biomass and energy production of the oak trees do not directly indicate the energy available to the secondary consumer, as energy is lost at each trophic level through processes such as respiration and non-predatory mortality. Additional information on the trophic interactions and energy flow in the ecosystem is needed to make this calculation.

Soils developed and allowed bacteria and microbes to grow.
Soils developed and allowed bacteria and microbes to grow.
Water condensed on the ground and cooled the Earth.
Soils developed and allowed bacteria and microbes to grow.
Cause: Development of soil.
Feedback response: Bacteria and microbes adapted to live in soil, and their activity led to the breakdown of rocks and the release of nutrients that further supported the growth of vegetation. The vegetation, in turn, modified the soil by contributing organic matter and increasing water-holding capacity, creating more diverse habitats for microorganisms and leading to further coevolution of soil and biota.
Over millions of years, at a convergent boundary, rocks are pushed up against each other, creating a small set of hills. The hills are right on the ocean’s shoreline. The ocean water constantly beats on the rocks, taking small pieces of the rock back with it each time. The strong ocean winds also take away pieces of the rock constantly, carrying them into the ocean or other nearby areas. This causes the rock structure to have a unique, jagged, and beautiful shape.
