Chapter 3 Notes Ecosystem Boundaries Biotic and abiotic components of an ecosystem provide the boundaries that separates them from one another Some have a well-defined boundaries: Like a cave Scientist might define a terrestrial ecosystem as the range of a particular species of interest Ecosystems occur in a wide range of sizes Ecosystem Process Each ecosystem interacts with surrounding ecosystems Change in ONE ecosystem can affect the global environment Photosynthesis and Respiration Nearly all of the energy that powers ecosystems comes from the sun Plants, algae and other organisms have the ability to convert the suns solar energy to usable from of energy, these are called producers/autotrophs

Ecosystem Energetics Laws of Thermodynamics 1st ? Energy can neither be created nor destroyed, only transformed from one type to the other All energy in an ecosystem ultimately comes from the sun 2nd ? In any transfer of energy, energy is lost. Energy is constantly being lost to the environment as heat Primary Productivity Primary Productivity is the production of organic compounds from atmospheric or aquatic CO2, principally through the process of photosynthesis Plants use the product of photosynthesis in 2 ways 1. Plant structures such as proteins, cells, tissues (building the plant body) 2. Fuel for Respiration. This powers such processes as growth, transpiration, reproduction, etc. Gross primary productivity (GPP) ? total amount of energy from photosynthesis

Chapter 25- Origin of life on earth The earth is estimated to have formed about 4.6 years ago condensing from a cloud of dust and rock. For the first few hundred millions years the Earth was being bombarded by huge chunks of rock and ice. The collisions created enough eat to vaporise the adavible water and prevent seas from forming. The early earth had a reducing atmosphere (electron adding) and there was no oxygen in the atmosphere, and as a result there was no need for an ozone layer to protect the earth from high levels of UV radiation.

Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 10: Photosynthesis This chapter is as challenging as the one you just finished on cellular respiration. However, conceptually it will be a little easier because the concepts learned in Chapter 9?namely, chemiosmosis and an electron transport system?will play a central role in photosynthesis. 1. As a review, define the terms autotroph and heterotroph. Keep in mind that plants have mitochondria and chloroplasts and do both cellular respiration and photosynthesis! Autotroph: An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. Autotrophs use energy from the sun or from oxidation of

Catabolic Reactions -These types of reactions break down large molecules into smaller ones. These reactions release energy. Anabolic Reactions -These types of reactions build large molecules from smaller components. These reactions consume energy. ATP-The main form of cellular energy. These molecules have a structure that is easy to form and easy to break to access the stored energy. Entropy - A measure of the disorder of a system. The amount of free energy lost to the environment is an example Polarity - Uneven distribution of charges across a molecule. Hydrogen Bonding - Attraction between positive charge on a hydrogen in a dipole and the negative end of another molecule. Think water! Adhesion - The attraction of a water molecule to another substance

Eukaryotic Diversity Campbell AP Biology

Overview: AWorld in a Drop of Water ? In the past, taxonomists classified all protists in a single kingdom, Protista. ? However, it is now clear that Protista is in fact paraphyletic. ? Some protists are more closely related to plants, fungi, or animals than they are to other protists. ? As a result, the kingdom Protista has been abandoned. ? Various lineages are recognized as kingdoms in their own right. ? Scientists still use the convenient term protist informally to refer to eukaryotes that are not plants, animals, or fungi. Concept 28.1 Protists are an extremely diverse assortment of eukaryotes ? Protists exhibit more structural and functional diversity than any other group of organisms.

Vocabulary Entropy- a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system Catabolism- the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism. Anabolism- the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy; constructive metabolism. Cellular Respiration- the metabolic processes whereby certain organisms obtain energy from organic molecules Glycolysis- the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Vascular Tissue and Transport VASCULAR TISSUE & TRANSPORT Plants rely on specialized tissue, called vascular tissue, to transport water, nutrients, and the products of photosynthesis around the plant. The two types of vascular tissue are: xylem (zy-lum) phloem Water Transport Xylem - Transports water from the roots up to the rest of the plant in one way flow. Tracheids - Hollow cell in xylem with thick cell walls that resist turgor pressure Water Transport Water rises through the thin tubes by a process called capillary action (cohesion of water molecules and adhesion to solid surface). The thinner the tube, the higher the water will rise.
