Why are food chains limited in how long they can be?
plss help

Answers

Answer 1

Answer:

Energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from its prey's body. However, these transfers are inefficient, and this inefficiency limits the length of food chains.

usain bolt, a world champion sprinter, can run a 10-meter split in 0.82 seconds. say you obtain a quadriceps muscle sample from usain bolt and compare it to one from a 25-year-old male long-distance runner. what differences do you expect to observe between those two muscle samples? select all that apply.

Answers

A quadriceps muscle sample from Usain Bolt and compared it to one from a 25-year-old male long-distance runner, and it is seen that there are more fast-twitch fibers and red and white muscle fibers of larger cross-sectional area in Usain Bolt's leg muscles.

What is the distinction between fast-twitch and slow-twitch muscles?

Athletes who run fast, such as sprinters, have more fast-twitch muscle, which is called "white muscle," as they need more energy for a short period of time, and as a result, the muscles anaerobically respire. The slow twitch muscle, called "red muscle," is more commonly seen in the long distance runner, such as in the marathon, and these runners need a continuous supply of energy for a long time, so aerobically the muscle respires.

Hence, a quadriceps muscle sample from Usain Bolt was compared to one from a 25-year-old male long-distance runner, and it was seen that there are more fast-twitch muscle fibers and red and white muscle fibers with a larger cross-sectional area in Usain Bolt's leg muscles.

the sun helps plants transform carbon dioxide into a simple carbohydrate called

Answers

Hi! Your answer is glucose.

What exactly is glucose? It originates from Greece, where it translates to "sweet." It's a type of sugar.

Good luck on your science!

The sun helps plants transform carbon dioxide into a simple carbohydrate called glucose.

What is carbohydrate?

Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.

Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.

In the oxidation-reduction process known as photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized.

The process by which light energy is transformed into chemical energy in the form of sugars is known as photosynthesis. Using light energy, glucose (or other sugars) are created from carbon dioxide and water, with oxygen being released as a byproduct.

Thus, the carbohydrate called glucose is formed by the reaction of sun in plants.
