2/4 Daily Catalyst Pg. 14 Producers/Consumers 1. What is the relationship between a community and a population? 2. Edduan is studying red lizards in the desert biome. He is studying a 3,000 square mile area. In 1,000 square miles, he counts 600 lizards. Approximate how many lizards live in the 3,000 square mile desert. 3. What type of survivorship curve would you expect of an organism that produces 8 offspring with minimal parenting after the offspring are born.

Survivorship Curve Lab Directions: After you have read the lab, as a group formulate your hypothesis about the following question. Which population will have a higher life expectancy? Population A or B? Every member of the group will need the hypothesis, chart, results, conclusions and post lab questions completed in their notes. Time: 20 minutes Noise: 2 (with group)

2/4 Essential Questions What are the roles of producers and consumers? How does taxis behavior effect producers? What is the beginning of energy transfer (food webs)?

What is Ecology? Refresher! In this unit we will learn… How species interact with each other How species interact with their environment How populations respond to changes in the environment and resource changes

2/4 Notes Producers Key Points

There are two ways organisms receive energy Producers Consumers Definition: produce their own energy Ie: plants AKA: Autotrophs

Meaning of terminology Key Point #1: Autotrophs Auto= self Troph= food

There are two ways organisms receive energy Producers Consumers Definition: produce their own energy ie: plants AKA: Autotrophs How?

How organisms create energy Key Point #2: Plants utilize energy from the sun in a reaction called ________________. PHOTOSYNTHESIS

There are two ways organisms receive energy Producers Consumers Definition: produce their own energy ie: plants AKA: Autotrophs How? Photosynthesis

Why should we learn about plants? Plants use energy from the sun and then other organisms eat plants! We have to know about plants because they help provide energy to all living things.

Just like all living things, plants do the MR GORE things. MR GORE is the acronym we use for plants.

Metabolism M- metabolism Key Point #3: Plants create glucose (food) in chloroplasts during photosynthesis.

Reproduction

Reproduction Key Point #4: Plants reproduce SEXUALLY and ASEXUALLY Plant sex cells: -male: pollen -female: seeds Pollen is delivered from one flower to another by either wind or other animals.

Growth G- growth Key Point #5: Plants continue to grow throughout their whole life. Apical meristem Do animals? Example: Apical meristems divide rapidly and replace old dead cells with new cells.

Organization Key Point #6: Plants are made up of _____________ cells. EUKARYOTIC

Response R- response Key points #7: Plants respond to stimuli Tropisms Stimuli- cause a change

Response Environmental stimuli signal growth responses called TROPISMS in plants. Phototropism: grow towards light Gravitropism: Stems grow upward and the roots grow downwards Thighmotropism: growing around an object

Today, there are over 260,000 species of flowering land plants. Evolution Originally there were just simple green algae water plants. The first land plants didn’t form until 475 million years ago. Today, there are over 260,000 species of flowering land plants.

There are two ways organisms receive energy Producers Consumers Definition: produce their own energy ie: plants AKA: Autotrophs How? Photosynthesis M- metabolism R- reproduction G- growth O- organization R- response E- evolution Definition: consume energy ie: animals AKA: heterotrophs

Meaning of terminology Key Point #8: Heterotrophs Hetero= different Troph= food

Animals cannot produce their own food so they get their energy through eating other organisms

There are three types of consumers- based on what they consume! Key Point #9: Types of consumers HERBIVORE- eats plants CARNIVORE-eats meat OMNIVORE- eats plants and meat

Photosynthesis M- metabolism R- reproduction G- growth O- organization R- response E- evolution Definition: consume energy ie: animals AKA: heterotrophs How? Carnivore Herbivore Omnivore

Are all consumers created equal? No, they are not! There are different levels of consumers depending on what they eat. This is the beginning of a food chain!

Read the following article on gravity’s effect on the growth of plants.

What type of survivorship curve would a human being display? 3. What type of growth model do populations show in a stable environment? 4. True or false, Frogs show r selection factors because they take good care of their offspring.

2/4 Exit Ticket #4 1. What would likely be the cause of bushes of one species growing in one area in a uniform spacing pattern? a. random distribution of seeds b. interactions among individuals in the population c. chance d. the varied nutrient supplies in that area e. variation in sunlight B, human plants the seeds in that pattern 2. What is the likely dispersion pattern: fish that swim in schools- Clumped seabird nesting on a small field- Uniform thistles growing in a fairly uniform field?- Random 3. What is the most common type of dispersion? Why? Clumped because of protection, hunting, mating, and social behavior
