In a food web, which type of organism receives energy from every other type? producer decomposer carnivore herbivore :10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Level A is composed of carnivores. producers. herbivores. omnivores. :10 carnivores. producers. herbivores. omnivores. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

primary succession. secondary succession. coevolution. When the settlers arrived in New England, many forests were turned into fields. Eventually, some fields were abandoned and then grew back into forests. This is best described as primary succession. secondary succession. coevolution. niche realization. :10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Succession is an organism’s ability to survive in its environment. :10 an organism’s ability to survive in its environment. the number of species living in an ecosystem. the regular progression of species replacement in an environment. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Ecology is the study of the interaction of living organisms :10 Ecology is the study of the interaction of living organisms with one another and their communities. with one another and their physical environment. and the food they eat. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Essay What is a keystone species and how does it affect an ecosystem Types of succession – be able to explain them Can you draw a food pyramid and what are the trophic levels, explain them What are the importance of decomposers
