Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat
Explanation:
<span>An ice age is the amount of the Earth's water that is locked up on land in the form of glaciers.
</span>According to the scientists, an ice age occurs every 100,000 years. There are five major ice ages in the Earth's history. That are the Andean-Saharan, Huronian, Karoo Ice Age, Cryogenian, and the current Quaternary glaciation.
But, If we entered another ice age currently, it would increase the amount of locked water in the form of glaciers and hence it would have huge consequences for human civilization and the ecosystem.
Producers provide oxygen gas as a result from photosynthesis - something that almost all other organisms at high trophic levels need
Reabsorption of filtered glucose from the lumen in the pct is largely by means of: secondary active cotransport.
Nephron is the functional unit of the kidney associated with removing waste products from the blood. It achieves the function by performing filtration which results in formation of urine. A nephron is divided into two parts namely renal corpuscle and renal tubule. Renal corpuscle is associated with filtration and renal tubule mainly performs reabsorption.
Renal tubules are further divided into Proximal Convoluted Tubule (PCT), loop of Henle, Distal Convoluted Tubule (DCT) and collecting duct. PCT and DCT are mainly linked with reabsorption and secretion respectively. Reabsorption in PCT occurs via cotransport. Here, glucose is reabsorbed along with sodium ions via SGLT2 cotransporter. Specifically, the reabsorption method is termed as sodium-coupled secondary active transport.

id say the first one and the third one, sorry if it’s wrong
