Biomass is a term used to measure the amount of energy in a biotic substance. Biomass is the energy that could be harvested from that plant. The plant itself doesn't produce biomass. Plants do produce O2 as a by-product of respiration, photosynthesis. Plants also produce various carbohydrates which are used by the plant to provide energy needs of the plant and nutrients necessary for the plants growth and ongoing processes.

Two ways by which plants get nitrogen compounds?

Plants obtain nitrogen compounds through the uptake of nitrate and ammonium ions from the soil through their root systems. Additionally, some plants have symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that can be used by the plants.


Can plants absorb nitrogen compounds from soil on their own?

Yes. Vascular plants can absorb nitrogen compounds such as nitrates from the soil on their own.What plants can't do on their own is fix nitrogen from the air into nitrogen compounds. Some plants including legumes (such as peas, beans, lupins) and casuarinas form symbioses with nitrogen-fixing bacteria to form nitrogen into nitrogen compounds.


What plants can grow well in chalky soil?

Plants that thrive in chalky soil include lavender, yarrow, columbine, and sedum. These plants are well adapted to the alkaline nature of the soil and can grow successfully in such conditions. Make sure to also consider the specific light and moisture requirements of each plant when selecting for your garden.


Which element found in the soil is used by plants in the form of chemical compounds?

Plants use nitrogen in the form of chemical compounds such as nitrates, ammonium, and amino acids found in the soil. Nitrogen is essential for plant growth and is a key component of proteins, chlorophyll, and nucleic acids.


Do plants grown hydroponically or in soil?

Plants can be grown both hydroponically and in soil. In hydroponic systems, plants grow in a nutrient-rich water solution without soil. In traditional soil-based gardening, plants grow in natural soil with nutrients available for uptake. Both methods have their advantages and can support healthy plant growth.
