Nitrogen enters the food chain... 1. primarily through soil-dwelling bacteria that "fix" nitrogen by attaching it to other atoms

2. from the atmosphere when "fixed" by the photosynthetic machinery of plants 3. when rocks dissolved by rainwater become soil, which is then utilized for plant growth 4. through soil erosion followed by runoff into streams and ponds 5. through methane, produced by herbivores as a by-product of the breakdown of plant material.

Answer:

The correct answer will be Option-1.

Explanation:

Nitrogen fixation is the process by which the atmospheric nitrogen enters the living sphere of the earth. The atmosphere is the largest reservoir of nitrogen in which nitrogen accounts for 78% of the total gases.

The atmospheric nitrogen is fixed through three pathways: lightning, man-made a method like Haber's process and the Biological fixation.

Biological fixation accounts fro 92% of the total nitrogen fixation which is performed by the few bacteria which contains the Nitrogenase enzyme and break down the N₂ to NH₃. The bacteria like<em> Rhizobium</em> is the leguminous bacteria which fixes the nitrogen.

Thus, Option-1 is the correct answer.

Bas_tet [7]

Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase

Here is a word equation for the hydrolysis of lactose:

lactose + water → galactose + glucose

Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.

Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of:_________
pogonyaev

Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of about 90% of all plants.

Mycorrhizal fungi are a symbiotic combination of fungi and plants. The term mycorrhiza refers to the role of fungi in a plant's rhizome, its root system. Mycorrhizae play an important role in plant nutrition, soil biology, and soil chemistry.

In mycorrhizal organization, the fungus resides in the root tissues of the host plant, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in extrinsic fungi.

The association is sometimes reciprocal. In some species or in specific cases, mycorrhizal fungi may have a parasitic association with the host plant.

Mycorrhizae are generally divided into ectomycorrhizae and endomycorrhizae. These two types are distinguished by the fact that mycelium of mycorrhizal fungi does not penetrate individual root cells while mycelium of endophytic fungi penetrates the cell wall and penetrates the cell membrane.
