Carbohydrates most abundant biomolecules on earth, are produced by :
- All bacteria, fungi and algae
- Fungi, algae and green plant cells
- Some bacteria, algae and green plant cells
- Viruses, fungi and bacteria
The Correct Option is C
Solution and Explanation
Carbohydrates, including cellulose, starch, glycogen, glucose, fructose, and others, constitute the most prevalent biomolecules on Earth. These carbohydrates are generated through photosynthesis, a process that involves the reduction of atmospheric carbon dioxide using light energy. Photosynthesis is primarily carried out by green plants, including aquatic algae, which convert carbon dioxide into carbohydrates. While some bacteria can also perform photosynthesis, their process differs in that they rely on chemical energy instead of light energy and do not produce oxygen as a byproduct, in contrast to the photosynthesis occurring in green plants.
So, the correct option is (C): Some bacteria, algae and green plant cells

Environmental Issues
Environmental issues refer to problems that arise from human activities that negatively impact the natural environment. These issues have far-reaching consequences on the earth and its inhabitants, including plants, animals, and humans.
Some of the major environmental issues include climate change, pollution, deforestation, and loss of biodiversity. Climate change is caused by the accumulation of greenhouse gases in the atmosphere, leading to global warming and changes in weather patterns. Pollution is the release of harmful substances into the environment, such as air pollution from vehicle exhausts and industrial emissions or water pollution from oil spills and agricultural runoff.
Deforestation is the clearing of forests for human activities such as agriculture and logging, leading to habitat destruction and loss of biodiversity. Biodiversity is the variety of plant and animal species in an ecosystem, and its loss can lead to ecological imbalances, reduced food security, and the spread of diseases.
Other environmental issues include land degradation, resource depletion, and waste management. Land degradation is the deterioration of soil quality due to activities such as overgrazing, overuse of fertilizers, and deforestation. Resource depletion refers to the depletion of natural resources such as water, fossil fuels, and minerals. Waste management refers to the proper disposal and treatment of waste, which can cause health and environmental problems if not handled correctly.
Overall, environmental issues require collective action and effective policies to reduce their impact and preserve the natural world for future generations.
