Ecosystem stability depends on food, water, shelter, and biodiversity. These factors provide the necessary conditions for the survival and growth of organisms, and biodiversity plays a vital role in ecological balance.
The main components needed to ensure
ecosystem stability
are: food, water, shelter, and biodiversity (option c). These factors are fundamental necessities for all living organisms.
Food
provides energy for their growth and reproduction.
Water
plays a crucial role in various life processes.
Shelter
protects organisms from harsh environmental conditions and predators. Finally,
biodiversity
improves ecosystem productivity and resilience, as different species play unique roles in maintaining ecological balance. The presence of a diverse range of species also allows for more robust responses to environmental changes.

Natural gas forms from the remains of buried plants and animals. This statement is True.
Natural gas is primarily formed from the remains of buried plants and animals that existed millions of years ago.
The process starts with the accumulation of organic material, such as dead plants and microscopic organisms, in an anaerobic environment, like swamps or seabeds.
Over time, as more layers of sediment cover the organic matter, heat and pressure increase, transforming the organic material into hydrocarbons, including natural gas.
The process of converting these organic remains into natural gas is known as thermogenic gas formation.
While there are other sources of natural gas, such as methane produced by methanogenic bacteria, the majority of natural gas deposits are indeed derived from ancient organic material.

Answer:
true
Explanation:
B. A path of chemical to mechanical energy.
C. A path that an electric current follows.
An electric circuit is a closed loop or pathway along which an electric current flows
The best definition of an electric circuit is Option C: A path that an electric current follows.
An electric circuit is a closed loop or pathway along which an electric current flows. It consists of various components such as a voltage source, conductors, and load. For example, when you plug in an electrical appliance like a light bulb into a wall socket, the circuit is completed, and electricity can flow from the source to the load, allowing the bulb to light up.

B) They are natural polymers composed of repeating monomeric units.
C) They are formed during exergonic metabolic reactions in a cell.
D) They have characteristics similar to the elements making them up.
Answer:
B) They are natural polymers composed of repeating monomeric units.
Explanation:
A polymer is a chemical molecule formed by many repeating units (monomers). A protein consists of many amino acids (monomers of proteins) joined together through peptide bonds that form a long chain, in the case of lipids, the monomers are fatty acids and glycerol and finally, in polysaccharides, simple sugars are the repeating units.
I hope you find this information useful and interesting! Good luck!
proteins, lipids, and polysaccharides are similar in the way that they are natural polymers composed of repeating monomeric units. Correct option is B.
Proteins, lipids, and polysaccharides are all biological macromolecules that share the characteristic of being natural polymers composed of repeating monomeric units.
Proteins are composed of amino acids, which are the monomeric units. Amino acids are linked together by peptide bonds to form polypeptide chains, which then fold into complex three-dimensional structures to perform various functions in cells.
Lipids, although not strictly polymers in the same way as proteins or polysaccharides, can be considered as macromolecules. They are composed of various hydrophobic molecules, such as fatty acids and glycerol. Lipids are characterized by their hydrophobic nature and are involved in functions such as energy storage, insulation, and forming cell membranes.
