Mixed Science Flashcard

Front

What converts nitrogen gas into a usable form for plants and animals?

Back

Bacteria convert nitrogen gas into a usable form for plants and animals through a process called nitrogen fixation.

Front

What is the main difference between nuclear fission and nuclear fusion?

Back

Fission splits a larger atom into two smaller ones, while fusion combines two smaller atoms into a larger one.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).

Front

Which organism would be at the top of a food chain?

Back

The hawk is typically at the top of a food chain as a predator.

Front

What needs to be placed where the X is in the formula for photosynthesis?

Back

Glucose is needed in the formula for photosynthesis.

Front

What is photosynthesis?

Back

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

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is the difference between an autotroph and a heterotroph?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy (e.g., animals).

Front

What is the function of chlorophyll in plants?

Back

Chlorophyll is the pigment that absorbs sunlight for photosynthesis.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates, condenses, and precipitates back to the earth.
