STUDY GUIDE page 61 CHAPTER 2 ASSESSMENT KEY CONCEPTS VOCABULARY Student is responsible for knowing and understanding key concepts. Answer & Explanation. 1: Organisms and Their Environment I. Organisms and Their Environment A. Food chains: Pathways for matter and energy FOOD CHAIN is a simple model that scientists use to show how matter and energy moves through an ecosystem. CHAPTER 2 ASSESSMENT Must turn into teacher Standardized Test Practice page 63 Answer questions #17 to #22. Two major types of kinds of ecosystems --- terrestrial ecosystems and aquatic ecosystem. Principles of ecology chapter 2 answer key strokes. 2: Nutrition and Energy Flow Section Assessment page 57 Understanding Main Ideas Answer all questions: #1 to #4 Thinking Critically Answer #5 question.
EXPLAIN the difference between a niche and a habitat. Stuck on something else? Energy and trophic levels: Ecological pyramids An ECOLOGICAL PYRAMID can show how energy flows through an ecosystem. TRACE the path of energy and matter in an ecosystem. 3 page 39 and Figure 2. 1: Organisms and Their Environment C. Biosphere 1. Sharing the World 1. Principles of ecology pdf. Food webs A FOOD WEB shows all the possible feeding relationships at each tropic level in a community. Parasitism MUTUALISM is a symbiotic relationship in which both species benefit. Nutrition and Energy Flow C. Cycles in Nature 1. Biotic and abiotic factors form ecosystems E. Organisms in Ecosystems 1.
12 on pages 48 to 49 Notice that the order is autotrophs to first-order heterotrophs to second-order heterotrophs to third-order heterotrophs to decomposers (which is at every level of the food chain) An arrow is used to show the movement of energy through a food chain. Consider both factors when viewing a biosphere. 2: Nutrition and Energy Flow New Vocabulary and Review Vocabulary on page 46 Student is responsible for defining and understanding the vocabulary for this section. Thinking Critically page 62 Pick one question and answer. ABIOTIC FACTORS are the nonliving parts of an organism's environment such as the air currents, temperature, moisture, light, and soil. Principles of ecology chapter 2 answer key pdf. 1: Organisms and Their Environment E. Niche A HABITAT is the place where an organism lives out its life.
16 on pages 52 and 53. The phosphorus cycle Using Figure 2. Ex: ants and acacia tree – Figure 2. The producers: Autotrophs 2. Levels of Organization 3. VOCABULARY Student is responsible for defining, knowing and understanding all the vocabulary. Recall the conservation of energy and mass concept from 8th grade General Science. 1: Organisms and Their Environment D. Interaction within populations Levels include the organism by itself, populations, communities, and ecosystems. COMPARE the different levels of biological organization and living relationships important in ecology.
Interaction within communities BIOLOGICAL COMMUNITY is made up of interacting populations in a certain area at a certain time. PARASITISM is a symbiotic relationship in which a member of one species benefits at the expense of another species. Trophic levels represent links in the chain 3. Studying nature The study of plants and animals, including where they grow and live, what they eat, or what eats them, is called natural history.
Interaction within populations 2. A NICHE is all strategies and adaptations a species uses in its environment --- how it meets its specific needs for food and shelter, how and where it reproduces. Organisms and Their Environment F. Survival Relationships 1. Flow of Matter and Energy in Ecosystems 4. Organisms and Their Environment D. Levels of Organization 1. Parasitism SYMBIOSIS is the relationship in which there is a close and permanent association between organisms of different species. 1: Organisms and Their Environment F. Survival Relationships: three types SYMBIOSISIC RELATIONSHIPS 1. Trophic levels represent links in the chain Each organism in a food chain represents a feeding step, or TROPIC LEVEL, in passage of energy and materials. The packet is organized in a low-prep and easy-to-use printable format. The consumers: Heterotrophs AUTOTROPHS is an organism that uses light energy or energy stored in chemical compounds to make energy-rich compounds. The consumers: Heterotrophs B. This comprehensive Ecology packet is aligned with the National Science Education. Objective 2: Organism both cooperates and competes in ecosystem (i. e. parasitism and symbiosis).
The water cycle or hydrologic cycle 3. Ecology research C. The Biosphere 1. ANALYZE how matter is cycled in the abiotic and biotic parts of the biosphere. Also means living together. 19 on page 56, student shall be able to explain and describe the NITROGEN CYCLE. Ecological research ECOLOGY is the study of interactions that take place between organisms and their environment. Priority Academic Student Skills: P. A. S. Content Standard 4: The Interdepedence of organisms --- Interrelationship and interactions between and among organisms in an environment is the interdependence of organisms.
Matter, in the form of nutrients, also moves through, or is part of, all organisms at each tropic level. BIOTIC FACTORS are all the living organisms that inhabit an environment. CHAPTER 2 ASSESSMENT Must turn into teacher Vocabulary Review page 62 Answer questions #1 to #5 Understanding Key Concepts Answer questions #6 to #9 Constructed Response pg 62 Pick one question and answer. How Organisms Obtain Energy 1. Objective 1: Matter on the earth cycles among the living and nonliving components of the biosphere. The living environment The BIOSPHERE is the portion of the Earth that supports living things. The phosphorus cycle. 9 page 45 is a tick.
Failure to learn shall result in a decrease in grade. HETEROTROPHS is an organism that cannot make its own food and feeds on other organisms. Biotic and abiotic factors form ecosystems An ECOSYSTEM is made up of interacting populations in a biological community and the community's abiotic factors.
