Answer:
Decomposers are essential to help an ecosystem to survive.
Explanation:
Decomposers are important because they are crucial for the proper functioning of ecosystems. They recycle the minerals found in dead plants and animals back into the food chain. Ecosystems do not waste energy or materials, and as such, the decomposers capitalize on any remaining energy in a dead organism and make the minerals available to the entire biome.
Without the actions of decomposers, ecosystems would quickly grind to a halt. The green plants, which start the food chain, are unable to grow without nitrogen, potassium and phosphorus. These minerals are released into the environment when decomposers digest their food.
Most decomposers are bacteria. However, many other types of decomposers do exist, including earthworms, protozoans, fungi and millipedes. Earthworms, for example, crawl through leaf litter and soil eating the remains of dead leaves and other organic matter. The earthworms catabolize the energy-rich molecules and excrete the inorganiccompounds. In this way, earthworms essentially produce soil.
Fungi are very important decomposers as well. Many grow in wounded, sick or dying trees. Fungi normally exist as tiny filaments that largely remain out of sight in the soil or within the wood of a tree. However, at certain times, the filaments produce a reproductive structure, known as a mushroom. Sometimes, these mushrooms are visible growing from the soil or out of the wood of a decaying tree.

roots
mitochondria
stems
leaves
The right answer is roots, stems and leaves.
Mitochondria and chloroplasts are not organs but organelles.
Plants, although of very varied morphologies, have in common (with the exception of a few rare groups) of possessing differentiated organs: a stem bearing itself leaves and buds, and for most of them, roots. These organs are themselves made of tissues, organized sets of specialized cells. Among the smaller plants are the mosses, whose leafy stem, a few millimeters to a few centimeters in height, is anchored to the ground by filaments. They have neither roots nor conductive tissues.
Answer: Single covalent bond in the long hydrocarbon chain.
Saturated fatty acids are long chains of hydrocarbon ( with single covalent bond) ending with the carboxylic group (-COOH). This means those fatty acids which possess only single bonds in their chemical structure are called as saturated fatty acids. They are densely packed, which makes them solid at room temperature.
Example- Lauric acid ( present in coconut oil). It has 12 carbon atoms in its chemical structure.
2. small intestine
3. large intestine
4. stomach
The most absorption of nutrients take place in small intestine. The correct option is B.
Thus, The digestive system's small intestine is where the majority of nutrition absorption takes place.
Villi and microvilli, small finger-like projections that line its walls, significantly increase the surface area that can absorb nutrients.
These structures make it easier for nutrients like carbs, proteins, lipids, vitamins, and minerals to enter the bloodstream and be carried to the cells of the body where they can be used for energy and other purposes. The liver and other organs process the nutrients that have been ingested after that.
Thus, The most absorption of nutrients take place in small intestine. The correct option is B.

The correct answer is option C which is globular. And the correct statement is:
Globular star cluster forms from tightly packed groups of older stars.
The type of star cluster that forms from tightly packed group of older stars is called “The Globular cluster.”
Globular cluster is known to contain large group of old stars that are tightly and closely packed accordingly in a symmetrical but spherical form.
Globular clusters are the largest and most enormous star clusters, and are known to usually appear in roughly spherical forms.
Globular clusters are usually formed through molecules of giant cloud, or enormous masses of gas that form stars due to their collapse. Notably, globular clusters cannot form today as a result of the current limited availability of free gas compared to its abundance at the early stage of the universe.
Globular clusters are found to be the oldest objects existing in the Galaxy. Globular clusters are said to contain between hundreds of thousands and millions of stars, and are heavily distinguished among other clusters due to their old age uniformity.
The relative ages of elements in globular clusters ranges from 11 billion to 13 billion years after being determined by comparing stellar population of globular clusters with stellar evolutionary models.
It should be noted that they could be as young as 9 billion years old based on modern developed research models.
