Answer:
The first trophic level
Explanation:
The most important trophic level in the ecosystem is the the first trophic level. This trophic level is dominated by the plants the furnishes the ecosystem with food.
- The ecosystem is made up of living and non - living components.
- To being with, the trophic levels are the feeding levels which corresponds with the energy levels.
- Now, the most important of all is the first trophic level
- It is made up of plants which are called producers.
- They use inorganic matter to produce food for the whole ecosystem.
- This food is the source of energy for all living activities in the system.
If a star of 50 solar masses were to supernova. It would most likely become a black hole.
A star is a hot body of glowing gas which starts its life in Nebulae. The stars vary in size, mass and temperature. The mass of a star ranges from 1/20 times to 50 solar mass.
The stage one of the stars is born in nebula, which is a region of very high density and then it gets condensed to a huge globule of gas and dust that contracts under its own gravity.
The next stage is a region of the condensing matter which starts heating up and glowing is known as Protostar. At stage three, hydrogen fuses and forms helium as the nuclear reactions start. Stage four is a Main Sequence star when it starts to release its energy, contraction stops and it begins to shine.
Some of the stars have mass more than 3 times of the Sun and up to 50 times the mass of the sun.
When the surviving core is between 1.5-3 solar mass, with higher contraction making it tiny and dense a Neutron star is formed. If the core is greater than 3 solar masses then the core further contracts to become a Black Hole.
Triglycerides are formed by combining glycerol and three fatty acids. Specifically, the hydroxil groups of the glycerol join the carboxyl group of the fatty acid to form ester bonds.
Phospholipids are made up of two fatty acids namely: long chains of hydrogen and carbon molecules and they are attached to the glycerol "head".
Based on their individual structure, the difference between the two is the number of fatty acids they both contain. Triglycerides has three fatty acids while phospholipids only have two.
Answer:
While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually.
