Do NowA trait in giraffes for the length of the neck of the organism is controlled by a gene. The dominant allele of the gene gives long necks while the recessive allele gives short necks. Use this information to answer the question below.

1. A giraffe has a short neck. What is/are its genotype(s)? bb2. A giraffe has a long neck. What is/are its genotype(s)? BB or Bb3. A giraffe’s genotype is homozygous recessive, how could this be abbreviated? bb4. A giraffe is heterozygous, what is its phenotype? Long neck

Do NowA heterozygous male is crossed with a heterozygous female. Use a Punnett square to answer the questions below.5. What is the offspring’s chance of being female? 50%6. What is the offspring’s chance of having a long neck? 75%

Ecosystems and AdaptationsLesson 6.2 – Organization of Living Things

I can describe the levels of organization (organism, population, species, community, ecosystem, and biome) of the living world. (3a)

1. The simplest organization of living things is the organism.

a. An organism is anything that carries out all functions of life such as reproduction, obtaining energy, growth.

i. For example a Chihuahua is an organism

I can describe the levels of organization (organism, population, species, community, ecosystem, and biome) of the living world. (3a)

b. All the organisms of that have similar characteristics and can breed (reproduce) with one another are considered to be the same species.

i. Chihuahuas are a member of the species Canis lupusii. All species are given a scientific name which is made up of two Latin words. It is usually written in italics.

I can describe the levels of organization (organism, population, species, community, ecosystem, and biome) of the living world. (3a)

2. All the organisms of one species in a specific area at a specific time would be called a population.

a. Members of a population compete with each other for resources such as food or space.b. If a scientist was studying a disease in the Chihuahuas living in New York City, he or she would be studying a population of Chihuahuas.

I can describe the levels of organization (organism, population, species, community, ecosystem, and biome) of the living world. (3a)

3. All the populations that live in a specific area at a specific time would be called community.

a. Populations interact with each other in many different ways. Some populations compete while others will help each other.b. If we were describing the community that the scientist was studying, we would have to name all of the different species of animals living in New York City.

I can describe the levels of organization (organism, population, species, community, ecosystem, and biome) of the living world. (3a)

4. An ecosystem is made up of one or more communities and their nonliving environment.5. A biome is a large group of ecosystems that have similar climates and organisms.

a. Biomes are mainly determined by temperature and the amount of precipitation they receive.

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

Fill in the chart below showing the following terms: biome, population, organism, community, and ecosystem.

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

1. All of the species living in a bayou in Shaw, Mississippi: community2. A single macaw named Rio living in a pet store in Minnesota: organism 3. All of the land and living things in the Mississippi Delta: ecosystem

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

4. All of the macaws living in the rainforests of Brazil: population5. All of the land in the southeastern United States which share a similar climate: biome
