Front

What is adaptation?

Back

Adaptation is a change in an organism that helps it survive in its environment. For example, the brown fur of a snowshoe rabbit changes to white in winter to blend in with the snow.

Front

Why are all animals on Earth dependent on the sun?

Back

All animals depend on the sun for energy because it is the primary source of energy for plants, which are at the base of the food chain.

Front

What does the tilt of Earth's axis affect?

Back

The tilt of Earth's axis affects the seasons. For example, during June, the Northern Hemisphere is tilted towards the sun, resulting in summer.

Front

What is the first step in engineering practices?

Back

The first step is to identify the problem that needs to be solved.

Front

What are flowers in terms of plant biology?

Back

Flowers are the reproductive structures of a plant, where pollination and fertilization occur.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the role of plants in the ecosystem?

Back

Plants produce oxygen and serve as the primary food source for herbivores, forming the base of the food chain.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit, such as bees pollinating flowers while obtaining nectar.

Front

What is predation?

Back

Predation is a biological interaction where one organism (the predator) hunts and eats another organism (the prey).

Front

What is the significance of the Earth's tilt?

Back

The Earth's tilt is significant because it causes variations in sunlight received at different latitudes, leading to seasonal changes.
