Semester 1 Biology Review

Front

What is the most energy efficient way for a lion to hunt?

Back

Hunting larger prey less often.

Front

How do animals obtain the nitrogen they need?

Back

From the food they eat.

Front

What is the unit of energy commonly used in biology?

Back

Kilocalorie.

Front

What does it mean when a cub belongs to a specific female in a study?

Back

It indicates the maternal lineage and tracking of offspring.

Front

What must be true about the energy cost of hunting prey for a lion?

Back

The energy cost to hunt the prey must be less than the energy the lion has stored.

Front

Define 'energy efficiency' in the context of hunting.

Back

Energy efficiency refers to the amount of energy expended in relation to the energy gained from the prey.

Front

What is the role of nitrogen in animal biology?

Back

Nitrogen is essential for the synthesis of amino acids and nucleic acids.

Front

Explain the concept of 'net energy' in hunting.

Back

Net energy is the energy gained from the prey minus the energy expended in hunting it.

Front

What factors influence a lion's hunting strategy?

Back

Prey size, energy cost, availability of prey, and energy needs.

Front

Why is hunting smaller prey more frequent less energy efficient?

Back

Smaller prey may require more frequent hunts to meet energy needs, increasing overall energy expenditure.
