Answer/Explanation:
From the diagram attached below, we can match the reproductive strategy or structure each species uses which ensures the survival of their offspring as follows:
1. Elephant => herds young in to center of group
The Elephant usually keep their young ones at the middle of the herds to prevent their young ones from being preyed on easily by predators.
2. Frog => Pduces many offspring at once to protect against high predation risk
The young one of frogs are easily preyed on by predators, and as such, to ensure more of their offspring survive, they produce so many offspring in a breeding season, in order to increase thee survival of their offspring to the next generation.
3. Pine cone => Protects offspring until environmental conditions are ideal for growth
