1st Semester Study Guide Answers: 

1 st Semester Study Guide Answers Made up of DNA Made of similar Chemicals Respond to stimuli Cellular Organization Ability to reproduce Use energy All grow and develop 1. What are the characteristics that all living things have in common? What are the 4 needs of all living things? Energy Water Living Space Maintains homeostasis

Page 1of Study Guide: 

Page 1of Study Guide Place where an organism obtains the things it needs to live, grow and reproduce is called a habitat. Bear-Forest floor; termites –fallen tree trunks; mushrooms- damp soil or forest floor A. Trees B. Grass C. Eagle or bird A. Air B. Sunlight C. Soil or temperature Ecology is the study of how all living things interact with each other in the environment.

Page 2 of Study Guide 8. What are the levels of ecological organization? List them on the pyramid. Think broader can this chart be extended?

Study Guide Page 2 Name 4 methods scientist use to determine the number of organisms in a given area. Sampling – an estimate or approximation based on data Direct observation- count one by one Mark and Recapture- animals are captured and marked Indirect observation- counting the number of nests, or their tracks Match the letters above with the correct definition below You count the number of birds in one square meter of trees--- B . Direct observation You count the number of nests in one square meter of trees--- D. Indirect observation You count the number of birds in one square meter and multiply by the size of the area say 100 square meters. --- A. Sampling You capture and place a number on each bird you find--- C. Mark and Recapture A limiting factor is an environmental factor that slows or stops the increase in the number of organisms within a population. A group of rabbits live near a group of foxes. In 2006 there was a drought and most of the plants in the area died. How did this affect the rabbit and fox population? It caused the population of rabbits to drop because they are herbivores that eat the plants and with their decline the fox population would also drop due to lack of food, since they feed on the rabbits. Weather conditions The three most common limiting factors are A. food, B. space, and C. weather conditions Carrying Capacity

Page 3 Adaptation- a characteristic that helps an organism survive in its environment --Predator adaptations help them to hunt and kill --Prey adaptations help the prey to hide from predators Adaptation Niche A. Symbiosis Competition Predation B, C, A 20. Mutualism B. Parasitism C. Commensalism D. Commensalism Name the 3 energy roles an organism can play in the ecosystem Decomposer B. Consumer C. Producer Name and define the 4 types of consumers . Omnivores- consumes both plants and animals Carnivores- Eats animals only Herbivores- Eats only plants/producers only Scavenger- Eats on the dead Add a producer ;2 more primary Consumers;2 more secondary Consumers 1 more decomposer

Page 5 Fill in the missing information to the energy pyramid and place 4 stars next to the level where you would find the most energy. Place 1 star on the level where you would find the least amount of energy. Also fill in the correct number of kilo-calories on each level.

Page 5 Biomes Name of Biome Rainfall in cm per year Common Flora Temperature Common Fauna Taiga or Boreal A. 30-90 cm Conifers, Evergreen trees, lichens, mosses B. -40 to 20⁰ C Lynx, deer, moose, elk, wolverines Rainforest 200-1,000 cm C. Bromeliads, Epiphytes D. 20 to 25⁰ C E. Toucan bird of Paradise, Proboscis Monkey, Gibbon Deciduous Forest F. 75 to 150 cm G. H. -30 to 30⁰ C I. Deer, Owl Tundra J. Less than 25 cm Low shrubs lichen no deep root systems, no trees, permafrost covers 75% of Tundra K. -40 to 18⁰ C Arctic foxes, wolves, polar bears, and caribou Grassland L. 50 to 90 cm Grasses Buffalo Grass Asters The soil is thin and dry for trees to survive M. -20 to 30⁰ C Prairie dogs, jack rabbits , deer mice, coyotes Desert N. Less than 25 cm Cactus P. -4 to 38⁰ C Snake, Roadrunner, Lizard

Skeletal You playing a video game at home what 3 systems make it possible for you to click the controller? 3, 5, 10 You get a cut while playing soccer which two systems work together to fight infection and close the cut? 4, and 8 In which system can you find the largest organ ? 8 Which system is responsible for creating gametes? 6 Which 2 systems work together to get oxygen to your cells? 1 and 7 The liver belongs to which system of the body? 2 and is the largest internal organ. The stomach belongs to which system in the body? 2 The kidneys belong to which system in the body? 9 The pancreas belongs to which system in the body? 2 and Endocrine Which system in the body produces blood cells ? 10 Which system of the body cannot regenerate damaged tissues? 5 Which system is responsible for eliminating solid waste? 2

Page 9 Photosynthesis Raw materials Carbon dioxide Water Products Glucose Oxygen Sunlight Chlorophyll Sunlight is needed for the reaction to occur so it is written above the line and it acts through Chlorophyll Photosynthesis occurs in the C hloroplast The process by which a cell captures the energy in sunlight and uses it to make food is called photosynthesis Pigments are colored chemical compounds that absorb light Stomata are small openings on the underside of leaves through which carbon dioxide enters a plant

Page 9 continued Respiration : 

Page 9 continued Respiration Raw materials Glucose Oxygen Products Carbon Dioxide water ATP How does fermentation differ from respiration? Fermentation is a way to get energy from cells but fermentation does not use oxygen while respiration does. Which type of respiration occurs in yeast? Alcoholic Fermentation occurs in yeast. Bakers and brewers depend on this type of respiration to occur. The stage of respiration that releases most of the energy in glucose occurs in the Mitochondria the power-house of the cell How are photosynthesis and respiration related? They are opposite equations. Where does cell transport take place? In the circulatory system What cell part allows molecules in and out? Cell membrane What are the 2 types of passive transport? Diffusion, and Osmosis Mitochondria

Page 9 : 

Page 9 Why are they called passive transport? Explain. Passive transport means that molecules are moved into the cell without the use of any energy by the cell. In diffusion and osmosis, molecules move from an area of high concentration to low concentration What types of molecules move by diffusion? Oxygen, Carbon Dioxide, small molecules What type of molecules moves by osmosis? Water How is active transport different from passive transport? The main difference between passive transport and active transport is that active transport requires the cell to use energy while passive transport does not.
