Large predators are found at higher trophic levels, what does this mean in terms of energy loss ?
VARVARA [1.3K]

Large predators are found at higher trophic levels because specialized bodies are needed to extract the small energy that gets to them.

The energy that gets to successive trophic levels decreases progressively because much of it is lost as heat. This means that a small percentage of the energy from the producers that form the bases of trophic levels to the predators that are somewhat at the top of trophic levels.

With big body size, the bodies of predators are organized into systems that work together to efficiently extract the small energy that gets to them from immediate lower trophic level.

More on the energy from trophic levels can be found here: brainly.com/question/13375401?

A graph titled "Average hamster weight (kg) vs. Amount of drug (mg/day)"
lakkis [162]

Explanation:

D. average hamster weight decreases with an increase in the daily amount of a drug until the hamsters reach a minimum possible weight.

Trend: There was a gradual decrease in the hamster's weight til a minimum was reached, after with the rate of its change in weight with treatment over time plateaued.

Trends are gradual notable changes or patterns over a series of data points on a line or curve of a graph. These allow for summarizing data and predicting results. A data summary provides a comprehensive report of experimental findings. This makes the analysis of data easier by answering key research objectives outlined in the experimental procedure.  Summaries allow for tracking trends and procedural changes, observations and potential; this makes it easier to arrive at conclusions faster.

<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

 

<span>
</span><span>The aim of the pyramid is to recommend ideal  rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>

A milk snake looks similar to the deadly coral snake. This is an example of A) warning coloration adaptive radiation B) cryptic
Damm [24]
In this case, c) mimicry is the answer. In Batesian mimicry in which harmless animals mimic toxic animals. In this case, I assume the milk snake is harmless and the coral snake is venomous. Since the milk snake has a trait similar to deadly coral snake, less animals would eat it thinking it is dangerous. Over time all the milk snake that look like the deadly coral snake would survive leading to evolution by natural selection. This would lead to more and more milk snake mimicking the resemblance of the deadly coral snake.

a) The deadly coral snake has a warning color adaptive radiation. If the question had described the environment and how the snaked adapted to the environment via warning coloration. This would've been correct.

b) cryptic coloration is more about camouflage with the environment. If the question had state how a certain feature help one of the animals blend into the background. This would've been correct.

d) I'm not sure whats different between this and a so i'll consider them both the same.
