The relevance of understanding animal behaviour in daily management is…

Answer 13

To encourage good and discourage bad behaviour

Knowing when an animal is dangerous

Knowing how to keep animals

Question 14

Ontogeny

Answer 14

How behaviour develops over an animals lifetime. E.g. how predators learn to avoid toxic/dangerous prey with experience > individually

Question 15

Phylogeny

Answer 15

How behaviour has evolved over many animals

Question 16

Answer 16

Yes

Question 17
