Answer:
1/4
Explanation:
Given the genotype of parent plants: Ggpp and ggPp. The parent plant with Ggpp genotype will form two types of gametes in 1:1 ratio= Gp and gp.
The parent plant with genotype ggPp would form two types of gametes in 1:1 ratio= gP and gp. The random fusion of these gametes from two parents would obtain progeny in the following phenotype ratio=
1/4 yellow purple: 1/4 yellow white: 1/4 green purple: 1/4 green white
Therefore, 1/4 of the total progeny would be "yellow and white".
Fertilizer Runoff
The excess nutrients provided by the fertilizer allow for rapid growth of algae and microorganisms. This fertilizer runoff can come from agricultural lands, or from residential areas.

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.
Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.
Explanation:
The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.
In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.
The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.
There will be a transfer of these inorganic nutrients to the trophic level in food chain.
Answer:
The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the
