Biodiversity

2. the sum of total of all genes in a population at a given time.
3. Biological communities where organisms interact with one another and with their physical environment.
9. The number of different species within a defined habitat/ a particular area/ region at any one time.
11. is the number / variety / range of species in a habitat OR it is the variety / types of alleles in a species/ population/ gene pool in an ecosystem.
13. Changes to programmed or instinctive behaviour making organisms better adapted for survival/ increases the survival chances.
14. The role of an organism within its ecosystem /habitat / environment. And how the organism or species interacts/exploits with its environment.
15. Organisms which can interbreed to produce fertile offspring.

1. A physical/ structural adaptation, it may be internal or external. Anatomical adaptations involve the form and structures of an organism.
2. variety of different alleles in a gene pool.
4. This is an area with particularly high level of biodiversity.
5. Involves the way the body of organisms work and include differences in biochemical pathways or enzymes.. These adaptations tend to be chances in the internal biochemical functioning of the organism in response to an altered environmental stimulus.
6. the breeding group of individuals of same species occupying a particular habitat and a particular niche
7. a place where organisms / species live
8. Species is native or restricted to one particular geographical area/ location in the wild.
10. a group of organisms of different species interacting in a particular area.
12. biotic and abiotic factors in a habitat.
