Biologists use their observations on a small island to construct the food web shown. Their calculations indicate that the produc

er level has about 150,000 kilojoules of energy available. How much energy is available to the primary consumers in this food web? Explain your calculation

I will explain my process using the image with my work and knowledge. So, the question is asking us how much energy is transferred from the producers to the primary consumers.

Step 1: I illustrated the question to get a visual representation by drawing a energy pyramid.

Step 2: Consider the 10% rule. It states that only 10% of energy is actually passed down from each tropic level. The 90% is gone as heat, used from metabolism, and etc by the organism. So, the producers passes down 10% of its energy to the primary consumers who are just one level above. The higher the organism in the pyramid, the less energy it obtains.

Step 3: Take the energy the producers have and multiply it by the 10%. Of course we cannot multiply by percentage so convert it into a decimal (0.10) and we get 15000 kJ

Step 4: 15000kJ of energy is transferred to the primary consumers

Can someone explain how it is possible for a single molecule of steroid hormone to create a significant and lasting response in
Mars2501 [29]

Steroid hormone

  • The cell signaling pathways induced by the steroid hormones regulate specific genes within the cell's DNA. The hormones and receptor complex act as transcription regulators by increasing or decreasing the synthesis of mRNA molecules from specific genes.
  • Steroid hormones are not able to target every cell within the body, so the overall response is slower. They bind to receptors on the cell's surface and the receptors aid in helping the steroid hormones enter the cell.
  • Hormones work by binding to protein receptors either inside target cells or on their plasma membranes. The binding of a steroid hormone forms a hormone-receptor complex that affects gene expression in the nucleus of the target cell.
  • Steroids pass into a cell's nucleus, bind to specific receptors and genes and trigger the cell to make proteins.

Alex_Xolod [135]

Answer:

Muscles can also receive messages from the brain when the body temperature decreases. They respond by shivering. Shivering causes the muscles to contract and relax quickly. This process generates heat.
