Describe temperate grassland ecosystem characteristics. Include climate, an example of a producer, and an example of a consumer
tester [92]

A grassland is a biome where dominant vegetation is grasses, a consumer of this biome can be a herbivore (e.g., a rabbit). Coral reefs are home to millions of species of marine animals.

<h3>Coral reefs, seaweed and forest biome</h3>

Coral reefs are fundamental for protecting wildlife in marine ecosystems.

Seaweed is a common plant in the Euphotic Zone (Sunlight Zone, also called Epipelagic Zone), along with algae and phytoplankton.

Temperate broadleaf forests are represented by areas with marked warm and cool seasons that show moderate annual average temperatures (3 °C  to 25 °C).

Examples of producers in a temperate broadleaf forest may be Eucalyptus species, whereas consumers may include, for example, elk, etc.

Under certain circumstances, potassium ions ( K + ) in a cell will move across the cell membrane from the inside to the outside.
dexar [7]

Answer:

8.18 × 10 ⁻²¹.

Explanation:

The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.

The change in the potential energy can be calculated as follows:

W = v2-v1 × q.

Here, the charge of the proton is considered because k+ ions has been used.

W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.

W= 8.18 × 10 ⁻²¹J.

Thus, the answer is 8.18 × 10 ⁻²¹.
