NEET BIOLOGY

Detailed explanation-1: -The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

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. 1 .

Detailed explanation-3: -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.

Detailed explanation-4: -Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.

Detailed explanation-5: -Levels of organization in ecology include the organism, population, community, ecosystem, biome, and biosphere.
