Energy is a fundamental component in an ecosystem and is contributed by the primary producers. how can light energy, in turn, support the consumers of an ecosystem? a. light energy is converted to chemical energy by primary producers and primary consumers. consumers belonging to higher trophic levels feed on them to gain energy. b. primary producers can only obtain energy from sunlight by photosynthesis and gain energy by feeding on them or other consumers which have consumed these producers. c. primary producers convert light energy to chemical energy using photosynthesis and consumers gain energy by feeding on them or on other consumers that have consumed these producers. d. primary producers convert light energy through chemosynthesis and consumers gain energy by feeding on them or other consumers which have consumed these producers.

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.
