Answer No 4:
Photosynthesis can be descried as a process in which carbon dioxide and water get converted into oxygen and glucose in the presence of sunlight. Energy from the Sun is essential for this process to occur. The light energy from the sun gets converted into sugars which are essential for providing plants with food. The sugar made during photosynthesis is also used for other cellular functions.
Answer No 5:
The non- photosynthetic organisms cannot make their own food. Hence, they feed on producers or other consumers. The initial source of energy on a food chain or food web are producers. As producers use light energy from the Sun to make glucose hence light energy is converted into usable energy for the producers as well as the consumers which eat the producers.
Also, as a result of photosynthesis ( which uses light energy) oxygen is produced. This oxygen is used for cellular respiration by the non- photosynthesis organisms. Hence, light energy is the initial energy source.
Answer:
A nutrient can be described as a substance which is used for the survival, growth and reproduction of an organism.
Three nutrients which plants require are:
NITROGEN (N): Nitrogen is important for growth and immunity. Without nitrogen, the plant will not be able to grow or produce immunity.
PHOSPHORUS (P): Strengthens root systems, capacity for seed creation, disease resistance, and pest prevention. Improves flowers and blooming. Also strengthens tissues and flavors in edibles and veggies. Without phosphorus, plants will not be able to produce sweet fruits.
CALCIUM
Strengthens and fortifies overall tissues everywhere. Also helps neutralize acidity, both within the plant and in its surrounding soil, for optimal health.
