An organism is multicellular and can be seen without a microscope. The bar graph shows the numbers of some of the organelles in one of the cells from the organism. From which kingdom is this organism? Options: Animalia, Archaebacteria, Fungi, Plantae.

Back

Plantae

Scientists conducted an experiment to determine how different wavelengths of light affected photosynthesis. They used two groups of the same plants. The leaves of Group 1 were covered with transparent green plastic. The leaves of Group 2 were not covered with any plastic. The results show that the plants photosynthesized best when their leaves were not covered in any plastic. Which hypothesis do the results support?

Back

If leaves are uncovered, then their chloroplasts will produce more oxygen than the leaves that are covered in green plastic.

Energy is transferred between trophic levels in a food pyramid. If 150,000 joules of sunlight are captured by plants, how much energy is transferred to secondary consumers?

Back

1,500 joules
