populations have characteristics such as | food chains and types of graphs |
types of graphs | s - curve, j - curve |
j - curve | exponential growth |
s - curve | limiting factors and carrying capacity |
food chains consist of | producers, decomposers, and consumers |
the 3 kinds of consumers are | primary, secondary, and tertiary consumers |
Nutrients in biosphere | nitrogen, oxygen, carbon, phosphorous |
Autotrophs | manufacture carbohydrates, proteins, fats, vitamins |
Heterotrophs | consume plants and animals |
Ecology is | study of living things and the natural environment |
10% rule | Only 10% of the energy at one trophic level can be used at the next trophic level |
Trophic levels | feeding level |
First trophic level | producers |
Second trophic level | primary consumers |
Food web | complex feeding relationships from interconnected food chains |
Food chain | sequence of organisms related to one another through predator-prey relationship |
Omnivores | eat everything |
Herbivores | eat plants |
Carnivores | eat animals |
