Answer:
The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).
The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.
Other differences are summarized in a tabular form attached below.

<u>Answer:</u>
The most appropriate answer option is: D) Saprophytes return organic material to the soil for use by living organisms.
<u>Explanation:</u>
A saprophyte, also known as a saprobe or saprotroph, is an organism (fungi) which feeds and grows on decomposing organisms. We also know that it secrete enzymes that digest components of cell walls, such as cellulose and lignin.
Saprophyte is an important part of the biogeochemical cycle as it decomposes the bodies of the dead organisms, recycles them and releases nutrients into the soil to be used by the living organisms.
<u>Answer:</u>
In the natural carbon cycle, the ocean influences climate by controlling CO2 levels primarily through <u>biological activity</u> and <u>massive geological events</u>.
<u>Explanation:</u>
Carbon flows in an interchange across each reservoir called the carbon cycle, which has gradual and rapid components. Any cycle shift which moves carbon from one reservoir places more carbon in another reservoirs.Changes that bring carbon dioxide into the environment contribute to higher Earth temperatures.
The carbon cycle appears to keep the balance over the long term that prohibits all Earth's carbon from atmospheric entry or being deposited entirely in rocks. That equilibrium helps to keep the temperature on Earth fairly stable, just like a thermostat.
