Ojeda Biology Classes

 A structural unit of all living things. The smallest unit classified as an living organism.

 Tissues are an ensemble of cells, they are not the same but the are of the same origin, that carries out an function.

 Organs are groups of tissue that perform different functions. There are many organs in the body like skin, kidney, liver, and etc.

Some types of organ systems are, Circulatory, Respiratory, Digestive, Nervous, and Reproductive.

 A single living organism. Example: Humans, Cows, Birds, Trees.

 A group of organisms of one type staying in the same area. An example is like and herd of cows on a plain, or the number of people living in Tuscaloosa.

 Different populations that live together. Examples: Cows, snakes grass, hawk.  They must all be LIVING Things  The community below includes the horses, cows, chickens & dogs

 These include the living & nonliving things found in the community (people birds water soil dogs etc.  Two examples of Ecosystems are wetlands and forests.

 Our Biosphere is made up of all of the biomes/ ecosystems on the planet earth.

A Pod of bottlenose dolphins living in a specific region can be identified as which level of organization? A. Biosphere B. Ecosystem C. population D. community

C population A population is a group of organisms of one type that all live in the same area.

Study the picture below Which level of organization is BEST represented by the entire picture? A. Organism B. ecosystem C. population D. community

B ecosystem An ecosystem is a community and its nonliving surroundings as labeled here Air Water Bird Fish Alligator Trees Bushes Grass

A group of cells that work together for a common function would MOST LIKELY be described as A. a tissue B. an organ C. an organelle D. a community

A. a tissue A tissue is a small group of cells used to make up organs such as the brain

Study the diagram below Which is a level of organization that could be represented by X? A. Plant B. Animal C. Biosphere D. community

A community is larger than a population but less inclusive than an ecosystem

Study the picture below Which level of biological organization results from the combination of the living organisms shown in the picture? A. Biosphere B. Ecosystems C. Populations D. community

A community is all living things (plants and animals) that live in a defined area

Which figure BEST represents the levels of organization in the ocean from largest to smallest? A.Community Organism Ecosystem Population B. ecosystem community population organism C. organism population community ecosystem D. population ecosystem organism community

B. Ecosystem, Community, Population, Organism Ecosystem, Community, Population, Organism is the levels of organization in descending order

Which sequence correctly identifies the levels of organization in a biosphere from most complex to least complex? A Organism  Population  Community  Ecosystem B ecosystem  community  population  organism C community  organism  ecosystem  population D population  ecosystem  organism  community

B. ecosystem  community  population  organism An ecosystem is a community and all its surroundings making it the most complex and an organism is one living object making it the simplest

Study the tables below. Ospreys, egrets and cranes were observed in an area around a small oxbow lake at Perry Lakes Park in Alabama Birds observed during one year BirdNumber observed Osprey63 Egret85 Crane22 Which student correctly categorized the observations according to the levels of organization in the biosphere StudentOrganismsPopulation(s)Communities A Student 1 B Student 2 C student 3 D student 4

C student 3 Since an organism is a single living thing you have to include all of them so =170 and a population is only one type of animal and three birds were being studied there were 3 populations and since a community is all the populations combined there is only 1 community

Study the Diagram below Forests, animals, sunlight, soil, water Oak forest, grey squirrels, deer Oak forest Oak tree A Organism B ecosystem C Community D Population Population community Ecosystem Organism Community population Organism Ecosystem Ecosystem organism Population Community Which example below represents the organizational levels shown in the diagram?

B ecosystem community population organism An ecosystem is a community and its nonliving surroundings. Communities are populations in a defined area. Populations are groups of organisms. An organism is a single living thing.

 Study the picture 10 A: Population B: Community C: Ecosystem* D: Organism Which level of organization is BEST represented by the entire picture? This includes the water,soil, animals & trees. Hint: This includes the water,soil, animals & trees.

 C. Ecosystem, because it is made up of the living & non living things.

 A scientist studied a coral reef in an ocean. The scientist made a data table to record what was observed. How many populations are represented by the data? 11 A: 2 B: 6 C: 67 D: 101

 The answer to that question is B. 6  It asked how many populations, and there are 6 populations. (Sea turtle, Sea Star, Nurse Shark, Clown Fish, Parrotfish, Sea urchin. Each TYPE is a different population.  The population of a town is the number of people that live there.

 A student preparing for a test in human anatomy studied the terms in the list. Which of the following represents a tissue in the human body? 12 Study the list of terms below. : osteocyte : stomach : muscle :digestive system A: Bone Cell B: Stomach C: Muscle D Digestive System Hint: This word ends in cyte which means CELL

 The answer to that question was C. Muscle Muscle is made up of cells that are similar to each other  because the stomach is an organ  an osteocyte is a bone cell  the digestive system is a whole system.

13 : Student Question A herd of animals in the same area is an example of, A.Population B.Biosphere C.Organism D.Ecosystem

 The answer is A. population  because, a population is a group of organisms of one type staying in the same area.

Great Job!!!
