Describe, in three or four steps, how toxins get more concentrated in organisms going up the food chain

Biology
1 answer:
Firdavs [7]3 years ago
7 0

Explanation:

Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.

These plants are eaten by primary consumers in low concentrations.

The toxin cannot be excreted so when the primary consumers are eaten by secondary consumers all the toxin is absorbed by the secondary consumers.

This repeats as secondary consumers are eaten by higher level consumers.

At each trophic level of the food chain, the toxins remain in the tissues of the animals - so the concentration of toxin becomes most concentrated in the body tissues of the animals at the top of the food chain.

Assoli18 [71]
The right answer is the dark reaction would stop happening.
The Calvin cycle (or dark reactions, independent of the sunlight) makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.There are three reactions of this cycle take place in the stroma of chloroplasts: the first of which is the fixation of carbon dioxide. which is a limiting step in this cycle.If a substance other than the components of the dark reactions absorbs and uses carbon dioxide, the carbon cycle will not be able to occur for lack of one of these ingredients which is the CO2.

Andrej [43]

Answer:

The correct answer will be

1. Inversion

2. 20-25 minutes

Explanation:

The injuries of the ligaments of the ankle are common among athletes like the anterior tibiofibular ligament sprain (AFTL) or calcaneofibular ligament (CFL) which are caused by the inversion of the flexed foot.

These cases of ankle sprains are treated with the rest and applying ice to the injured area for approximately 20-25 minutes repeated for  3-4 times per day.

Thus, Inversion and 20-25 minutes are the correct answer.

Answer:

Either (1.) Fossils or (2) Radiometric dating.

Explanation:

Fossils are an obvious answer to this, but radiometric dating is the method most scientists use to find the age of rocks. Radioactive isotopes break down predictably, so the farther along this process is, the older the rock is.

What is Grave's disease?
I am Lyosha [343]

Answer:

Graves´ disease is an autoinmmune disease that is caused when the immune system attacks the cells of the thyroid gland, which leads to an overproduction of the hormones secreted by the thyroid gland. This constant attack and destruction on the part of the immune cells causes the thyroid to increase in size, a condition that is commonly known as hyperthyroidism.

Hyperthyroidism can become a really serious issue because the excessive production of the hormones of the thyroid gland will increase the metabolic activity of all parts of the body and can, if left untreated, cause such serious conditions as blood clotting problems, type 1 diabetes, among others.
