Question

Consider the levels of organization of the biological world, and place each of these items in order from smallest level of organization to most encompassing: skin cell, elephant, water molecule, planet Earth, tropical rainforest, hydrogen atom, wolf pack, liver.

Answer 1

Answer:

The correct answer will be option-

Hydrogen (atom) →water (molecule)→ liver (organ) →skin (cell) →elephant (organism) → wolf pack (population) → tropical rainforest (ecosystem) →planet Earth (Biosphere).

Explanation:

The biological level of organization is the arrangement of the matter from the smallest to the largest in the hierarchy.

The smallest unit of matter is the atom which forms the molecules. These molecules together form the organelles which aggregate and form the basic unit of life called cell. The cells aggregate-gate and perform the same functions to form tissues which together form the organs. These organs constitute the organ system which forms the organisms. The organism together forms the population which form the community. The community becomes a part of the ecosystem which forms the largest level called the biosphere.

On the basis of this, the given options are arranged.
