Which of the following best defines species diversity?

• The number of different species present in a particular ecosystem

• The various biomes and the variability in these

• The different alleles possessed by a species and the genetic variation within members of a species

• Physical differences controlled by an individuals genes

Which of the following best defines genetic diversity?

• The number of different species present in a particular ecosystem

• The various biomes and the variability in these

• The different alleles possessed by a species and the genetic variation within members of a species

• Physical differences controlled by an individuals genes and environmental factors

Which of the following best defines 'ecosystem diversity'?

• The number of different species present in a particular ecosystem

• The various biomes and the variability in these

• The different alleles possessed by a species and the genetic variation within members of a species

• Physical differences controlled by an individuals genes and environmental factors

'Commensalism' is best described as:

• A relationship between 2 species in which one benefits and the other is unharmed

• A relationship between 2 species in which one benefits and the other is harmed or killed

• An interaction between 2 species in which the parasite feeds on the host causing it harm

• A close association between 2 organisms in which at least one benefits from the association

'Parasitism' is best described as:

• A relationship between 2 species in which one benefits and the other is unharmed

• A relationship between 2 species in which one benefits and the other is harmed or killed

• An interaction between 2 species in which the parasite feeds on the host causing it harm

• A close association between 2 organisms in which at least one benefits from the association

'Symbiosis' is best described as:

• A relationship between 2 species in which one benefits and the other is unharmed

• A relationship between 2 species in which one benefits and the other is harmed or killed

• An interaction between 2 species in which the parasite feeds on the host causing it harm

• A close association between 2 organisms in which at least one benefits from the association

'Amensalism' is best described as:

• A relationship between 2 species in which one benefits and the other is unharmed

• A relationship between 2 species in which one receives no effect or minimal benefits and the other is harmed or killed

• An interaction between 2 species in which the parasite feeds on the host causing it harm

• A close association between 2 organisms in which at least one benefits from the association

A symbiotic relationship between 2 organisms in which both benefit is known as:

• Amensalism

• Commensalism

• Mutualism

• Neutralism
