To produce hormones for growth
To regulate body temperature
To transport oxygen in the body
Where does most of the nutrient absorption take place in plants?
Flowers
Stems
Leaves
Roots
In a food chain, what is the term for an organism that produces its own food?
decomposer
producer
predator
consumer
What is the role of chlorophyll in photosynthesis?
Chlorophyll releases oxygen during photosynthesis.
Chlorophyll converts carbon dioxide into glucose during photosynthesis.
Chlorophyll absorbs light energy during photosynthesis.
Chlorophyll provides structural support to plant cells during photosynthesis.
Which organ in the digestive system produces enzymes to break down food?
Liver
Stomach
Pancreas
Kidney
What is the function of the stomata in plant leaves?
Photosynthesis
Seed dispersal
Water absorption
Gas exchange
What is the main source of energy for living organisms in an ecosystem?
Geothermal energy
Wind power
Nuclear fusion
Sunlight
How do plants obtain water and minerals from the soil?
Through photosynthesis
By absorbing it through their leaves
Via active transport
Through their root system via osmosis
What is the purpose of the small intestine in the digestive system?
To store excess water
To further break down food, absorb nutrients, and transfer them into the bloodstream.
To regulate body temperature
To produce hormones
What is the relationship between producers and consumers in a food chain?
Producers eat consumers in a food chain.
Producers and consumers have no relationship in a food chain.
Producers provide energy for consumers in a food chain.
Consumers produce energy for producers in a food chain.
What are the products of photosynthesis?
Water and carbon dioxide
Glucose and oxygen
ATP and NADPH
Starch and nitrogen
Which part of the plant is responsible for absorbing water and minerals?
Flowers
Roots
Leaves
Stems
What is the role of bacteria in the digestive system of animals?
Bacteria produce vitamins that are harmful to the animal's health
Bacteria help in breaking down food components that the animal's own enzymes cannot digest.
Bacteria contribute to the formation of solid waste in the digestive system
Bacteria prevent the absorption of nutrients in the digestive system
How does energy flow through a food chain?
Energy flows through a food chain by organisms exchanging it through physical contact
Energy flows through a food chain as organisms consume each other, starting with producers converting sunlight into energy and ending with decomposers releasing energy back into the ecosystem.
Energy flows through a food chain by organisms generating it from within their bodies
Energy flows through a food chain by organisms directly absorbing it from the atmosphere
