Answer:
□In field investigations, you are usually working with much larger animals than in the lab. In field investigations, it is much more difficult to separate your control and experimental groups.
In field investigation, you can learn from real life things, these have more ecological validity. In laboratory experiments, you work in an artificially designed system, it has low ecological validity. Field investigatios are more difficult to control and manipulate and replicate than laboratory investigations.
