Answer:
10000 units in the second
100000 units in the third
1000000 units in the fourth
Explanation:
According to the pyramid of energy, which describes how energy flows from one trophic level to another, only about 10% of the available energy is transferred to the organism in the next trophic level as a lot of energy (about 90%) is lost as heat.
In this question, in order to have 1000inits of energy in
- Second trophic level = 1000 = 10/100 × x
10x = 100000
x = 10000units of energy
- for third trophic level,
100 × 1000
= 100000 units of energy
- for fourth trophic level;
1000 × 1000
= 1,000,000 units of energy.
Saliva has a pH normal range of 6.2-7.6 with 6.7 being the average pH
A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.
- All living organisms, from bacteria to people, depend on amino acids for survival.
- The same 20 types of amino acids are present in all living things.
- Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
- Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

The answer is that the criteria of classification change with the improved understanding of organisms around us. During the time of Aristotle, not much was known about the living organisms. So, he classified them as he observed. Plants were classified into herbs, shrubs and trees; very much like what’s taught to a second grade student. Animals as Enaima and Anaima based on the presence or absence of RBCs. After him, Carolus Linnaeus tried his hand over classification. He came up with the 2 kingdom classification: Plants and Animals. He considered only a set of morphological and physiological criteria to decide the kingdom to which an organism belongs. It includes presence of cell wall, mode of nutrition, contractile vacuole, locomotion and others. Based on these criteria, he included widely differing organisms into a single kingdom, for example, fungi, bacteria, algae, and higher plants were included into plant kingdom just because they have cell wall as a common aspect. Then came, Ernst Haeckel, who came with a third kingdom of Protista to include unicellular organisms. Copeland gave a 4 kingdom classification segregating unicellular organisms into 2 separate kingdoms based on their nuclear structure. R.H. Whittaker came next introducing the most accepted 5 kingdom classification system. You should understand one thing that man’s knowledge of classifying organisms improved with the improving technologies available to him, which he exploited to very effective extent. Carl Woese gave the 6 kingdom classification and 3 domain system based on the 16S rRNA sequence.
Our understanding of organisms around us is improving day by day and the system of classification will also change further in pace with the improvement in technology.
I hope this helps! :D]
