Law Incorporation [45]
<h2>Energy </h2>

Explanation:

Energy flows in only one direction through an ecosystem

  • The Sun supports most of Earth's ecosystems
  • Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
  • The food energy created by producers is passed to consumers, scavengers, and decomposers
  • Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
  • Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
  • So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
  • Animals at the third level have only 10% as much available to them as those at the second level

This plant is a biennial, which means it will just take longer than a season to mature enough to produce flowers.

Since the Sweet William  plant did not flower last year when it was planted and this year also it did not bud till the spring. So, we can assume that these plant will need atleast two seasons to mature hence they are biennials.

Depending on the life span, plants are classified as annuals (one season), biennials(two season) and perennials (more than two years).
