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.

a. hydrogen atom, water molecule, skin cell, liver, elephant, wolf pack, tropical rainforest, planet Earth
b. hydrogen atom, skin cell, water molecule, liver, elephant, wolf pack, tropical rainforest, planet Earth
c. hydrogen atom, skin cell, water molecule, liver, wolf pack, elephant, tropical rainforest, planet Earth
d. water molecule, hydrogen atom, skin cell, liver, elephant, wolf pack, tropical rainforest, planet Earth

Answer 1

The hierarchy of biological organization from the smallest to largest is: hydrogen atom, water molecule, skin cell, liver, elephant, wolf pack, tropical rainforest, and planet Earth.

Step-by-step explanation:

When considering the levels of organization of the biological world, the correct sequence from the smallest level of organization to the most encompassing is: hydrogen atom, water molecule, skin cell, liver, elephant, wolf pack, tropical rainforest, planet Earth.

1. The hydrogen atom is the smallest unit and forms the basis of chemistry and biology, as atoms combine to form molecules.
2. A water molecule is a simple compound consisting of hydrogen and oxygen atoms.
3. A skin cell is a basic unit of life, composed of molecules and organelles.
4. The liver is an organ made up of tissues, which in turn are aggregations of cells.
5. An elephant is an organism, a complex living entity.
6. A wolf pack is a population of organisms that can interact within their environment.
7. A tropical rainforest is an ecosystem, consisting of many different species and their physical environment.
8. The highest level is represented by planet Earth, which encompasses all possible ecosystems and is part of the biosphere.

This hierarchy reflects increasing complexity and interaction among the components of biological systems.
