Answer:
Grass - grasshopper- man - bacteria.
Grass - rabbit- man - maggot.
Grass - cow - man - bacteria.
Explanation:
In these food chains, grass is the producer that provides food to primary consumer or herbivores such as grasshopper, cow and rabbit. These primary consumers are the food of secondary consumer such as human while when human die, it become the food of worms and decomposers such as maggot, bacteria etc. the nutrients releases by decomposers are used by producers for the production of food for themselves.
When one of the many pigments in the photosystem II absorbs light, the energy is directed inward from pigment to pigment until and unless it reaches the center of reaction. There, energy is conducted towards P680, thus, boosting an electron to a higher level of energy.

Stable isotopes refers to those isotopes that do not undergo radioactive decay. Oxygen atoms with atomic number of 16 and 18 are examples of stable isotopes. These isotopes of oxygen are usually found in substances such as polar ice and calcite. These substances are usaually measure with isotope fractionation and the ratios obtained are used to estimate water temperature of ancient oceans. From this, scientists can find out facts about ancient climates,
Answer:
21.81grams
Explanation:
According to the question, an agar medium requires the following ingredients: 21 grams (g) of
agar, 500 mg of dextrose, 3 dg of sodium, and 1 cg of potassium per 1,000 milliliters (mL) of distilled water.
Hence, the dry ingredient contain 21grams (g) of agar, 500milligrams (mg) of dextrose, 3decigrams (dg) of Sodium, and 1centigrams (cg) of pottasium.
We need to convert all units (not in grams (g)) to grams.
1grams = 1000milligrams
500 milligrams = 500/1000
= 0.500grams.
1grams = 10decigrams
3decigrams = 3/10
= 0.3grams
1grams = 100centigrams
1centigrams = 1/100
= 0.01 grams
Therefore, we have 21g, 0.500g, 0.3g, and 0.01g
The total dry weight of the ingredients will be:
21 + 0.500 + 0.3 + 0.01
= 21.81grams
