Answer:
1. A Struggle for Survival
2. survival will reproduce
3. Superior adaptive variation
Explanation:

2. Observation: variation in species: member of the same species have different ways of identification, which are color, sex, e.t.c

CONCLUSION: Superior adaptive variation will be passed on to offspring generation.
