Question

Ca

Answer 1

Answer:

1. cell
2. molecule
3. macro-molecule
4. organs
5. ecosystem
6. population
7. population
8. tissue
9. organism
10. Organism
11. organelle

Explanation:

Level of organisation or biological organisation is defined as a hierarchy of biological structures or systems that contribute to the life.

Level of organisation become complex as it increases in its hierarchy. Arrangement of biological organisation from simplest to complex include : Atom/Molecule/macro-molecules or bio-molecular complex, organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

• Blood is classified as a cell because it is the basic unit of life.
• Carbon dioxide  is classified as a molecule because it is made up of group of atoms.
• Carbohydrates are macro-molecule made up of group of bio molecules.
• Lungs are the organs which is a functional group of tissues.
• A desert, including animals, birds, plants, rocks, wind is considered as ecosystem because it include groups of organisms with the physical (abiotic) environment.
• All species of lizards in a rain-forest tree and Zebras in the zoo are classified as population because groups of organisms of the same species.
• Skin is considered as tissue because it is a functional groups of cells.
• One bacterium is considered as a organism because it is a living system consist of single cell.
• Dog is classified as organism as it is also a living system and made up of several cells.
• Chloroplast is a n organelle because it is a functional groups of bio-molecules and helps in several chemical processes.

Hence, the correct matches are:

Blood  - cell

Carbon dioxide  - molecule

Carbohydrates  - macro-molecule

Lungs  - organs

A desert, including birds, animals,rocks,  plants, wind  - ecosystem

All species of lizards in a rainforest tree  - population

Zebras in the zoo  - population

Skin  - tissue

One bacterium  - organism

Dog  - organism

Chloroplast  - organelle
