AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting

respond to it appropriately * Plants grow in response to: the wind‚ sunlight‚ root growth * Autotrophs- Photosynthesis * Heterotrophs- eat (engulf‚ ingest‚ absorb) * “see at many wavelengths of light” specifically detect‚ identify colors. * Detect and respond to pressure- (physical= wind‚ touch‚ other plants‚) * Efficient elegancy designed for life as a photosynthetic autotroph Senses of a plant “see”- light‚ many wavelengths “hear”- respond to different frequency of

increases initially‚ then sometimes declines slightly‚ and finally becomes more or less stabilized in the older stages. This trend applies particularly to the heterotrophs‚ whose variety is usually much greater in the later stages of the succession. 3. Net primary productivity (the amount of energy converted into products of photosynthesis by autotrophs‚ and available to heteroptrophs) increases until it reaches a stable high level. Change in net primary productivity during plant succession on an area

Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP

Chapter 4 Microscopes Two important factors in microscopy are: 1) Magnification: an increase in the object’s apparent size compared with its actual size. 2) Resolving Power: the ability of an optical instrument to show two objects are separate. Three types of microscopes: 1) Light Microscope (LM) M: 1000x RP 0‚2 micrometer (small bacterial cell) 2) Electron Microscope (EM) uses a beam of electrons to resolve electrons‚ better resolving powers than light microscope M:100‚000x RP 0

Premium Ecology Food chain Species
different species interact with each other within the ecosystem. A food chain usually starts with a producer‚ or an organism able to make its own food with either photosynthesis or chemosynthesis. This can also be referred to as an autotroph. Consumers‚ or heterotrophs‚ make the next level of the food chain. These can be either herbivorous‚ meaning they only consume producers‚ carnivorous‚ meaning they only consume other consumers‚ or omnivorous‚ meaning they eat both producers and consumers. Other
