Question

A gardener grows pea plants in two pots. One pot (A) has a low amount of essential nutrients in the soil, while the other pot (B) has normal levels of essential nutrients.
a) In the terrestrial ecosystems, what are the two most limiting essential nutrients for plant growth?
Answer: ……... & ……….. (Please spell out the whole word. DO NOT use the symbol. Enter your two answers in alphabetic order into the provided two blanks.)

b) Which pot you will expect to see better
plant growth based on the amount of nutrients in the pots? Answer...………. (answer A or B)

c) Pot ...……. (A or B) pea plants would benefit the most from the addition of Rhizobium Blank 5 (animal, plant, algae, fungi or bacteria) to the soil, because it helps with the supply of Blank 6 (what nutrient or what element) (Please spell out the whole word. DO NOT use the symbol) to boost plant growth.

d) The gardener can also inoculate mycorrhizae, which is one type of...……... (animal, plant, algae, fungi or bacteria) to the plant roots to boost plant growth.

Answer 1

A. Nitrogen and phosphorus are the two essential limiting nutrients to plant.

Nitrogen and Phosphorus are the limiting nutrients because plants require large amounts of them on a daily basis.A soil in limited supply of essential nutrients results in stunted growth or a lower number of plants in an ecosystem.

B. B pot will show better plant growth .

This is beacause the soil in pot B has nutriets such as Nitrogen and Phosphorus.

C. Pot A pea plants would benefit the most from the addition of Rhizobium bacteria to the soil, because it helps with the supply of nitrogen.

Rhizobium bacteria found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development. Since pot A pea plant lacks essential nutrient nytrogen in soil, the addition of rhizobium helps to provide nitrogen to the plant.

D. The gardener can also inoculate mycorrhizae, which is one type of fungi to the plant roots to boost plant growth.

Mycorrhiza is able to create a vast connection between the roots of a plant and with the soil around them, which allows for the fungus to uptake nutrients such as nitrogen and phosphorus for the plant and increase the surface area of the roots
