Across
- 1. The variety of life in a particular habitat or ecosystem, including the number of species, genetic diversity, and ecosystem diversity.
- 5. A substance that is formed as a result of a chemical reaction.
- 7. An imaginary line that separates the ecozones of Asia and Australia, marked by a notable difference in the species found on either side.
- 9. A group of organisms that can interbreed and produce fertile offspring.
- 11. A substance that undergoes a chemical change in a reaction.
- 12. The calculation of the quantities of reactants and products in chemical reactions based on balanced equations.
- 15. The simplest whole-number ratio of atoms of each element in a compound.
- 17. An imaginary line that divides the Earth into the Northern and Southern Hemispheres, located at 0 degrees latitude.
- 18. Line A proposed boundary separating the distribution of certain species, typically used to differentiate areas of significant ecological change or biogeographical zones.
- 19. A designated area, usually square or rectangular, used for sampling in ecological research. Researchers use these small plots to study plant and animal populations.
Down
- 2. A type of chemical bond formed when one atom donates an electron to another atom, resulting in the attraction between positively charged ions (cations) and negatively charged ions (anions).
- 3. Island in Indonesia that has most of Indonesia's biodiversity
- 4. A unit that measures the amount of substance, equivalent to 6.02×10^23 particles.
- 6. Scientist that said "In a chemical reaction, matter is neither created nor destroyed; the total mass of reactants equals the total mass of products."
- 8. A type of chemical bond formed when two atoms share one or more pairs of electrons, allowing them to achieve a full outer shell of electrons.
- 9. Scientist that develop a way to calculate biodiversity.
- 10. The variety of genes within a species, crucial for adaptability and survival.
- 13. Scientist that said "When two elements form more than one compound, the different masses of one element that combine with a fixed mass of the other element are in simple whole-number ratios."
- 14. Scientist that said "A chemical compound always contains the same proportion of elements by mass, regardless of the amount or source of the compound."
- 16. The relative number of individuals of each species in a given area, indicating how common or rare each species is compared to others.
