The earth’s five major environmental spheres are the biosphere, the atmosphere, the hydrosphere, the geosphere, and the cryosphere, where the biosphere contains living organisms and the cryosphere includes Earth's frozen water.
The biosphere is a complex and dynamic system composed of all living organisms and their interactions with one another, the atmosphere is composed of gases that are essential for life, such as nitrogen (78%), oxygen (21%), and trace gases like carbon dioxide, and the hydrosphere is composed of all the water on Earth, including oceans, lakes, rivers, etc. All these biosphere and atmosphere are interdependent.
Hence, the earth’s five major environmental spheres are the biosphere, the atmosphere, the hydrosphere, the geosphere, and the cryosphere, where the biosphere contains living organisms and the cryosphere includes Earth's frozen water.

Answer:
Environmental spheres refer to all the physical entities present in the environment. It majorly includes four spheres namely atmosphere, biosphere, hydrosphere and geosphere. However, some include cryosphere as a distinct portion.
1. Atmosphere: It refers to the gaseous blanket that surrounds the earth.
2. Biosphere: It includes all the living organisms including the environment they live in.
3. Hydrosphere: It represents all the water present on the earth. It may be in the form of rivers, lakes, glaciers, oceans, water vapors et cetera.
4. Geosphere: It refers to the solid portion of the earth. It includes crust, mantle, and core of the earth. It provides all the rocks and minerals required by the living organisms.
5. Cryosphere: It refers to the ice sheets (solid form of water) of the earth.
Answer:
Yes
Explanation:
definitely algal bloom is a significant change. What is more important is how the bloom affects other aquatic life. The bloom forms a dense "blanket" of growth, which as it grows rapidly and dies, decomposes. Bacteria feed on this rich organic stuff and use up the dissolved oxygen in the water. As the oxygen levels drop, fish and aquatic insects die. This is the result of the algal bloom.
Answer:
Homologous chromosomes
Explanation:
Homologous chromosomes are two pieces of DNA within a diploid organism carry the same genes, one from each parental source
Answer;
Carbohydrates;
The macromolecule that provides a person with most of the energy that is needed for daily activities is carbohydrates.
Explanation;
-Biological macromolecules fall into four categories: carbohydrates, proteins, lipids and nucleic acids. The body uses carbohydrates, lipids and proteins for energy.
Carbohydrates are the main source of energy and for structural purposes, Lipids are used to store energy; important parts of biological membranes and waterproof coverings, Nucleic acids helps to store and transmit hereditary or genetic information. Proteins functions as a source of energy and to control the rate of reactions and regulate cellular process.
