EVERYDAY SCIENCE

Detailed explanation-1: -They are organized from smallest to largest; organism, population, community, ecosystem.

Detailed explanation-2: -The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism. See below Figure 1.1.

Detailed explanation-3: -The correct order of the levels of organization from smallest to larges is: cell, tissue, organ, system and organism. In sequence, they are represented as atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, population, community, ecosystem, biome, and biosphere.

Detailed explanation-4: -Within the discipline of ecology, researchers work at five broad levels, sometimes discretely and sometimes with overlap: organism, population, community, ecosystem, and biosphere. Let’s take a look at each level.
