13.1 Ecologists Study Relationships TEKS 2F, 3E, 10C The student is expected to: 2F collect and organize qualitative and quantitative data and make measurements with accuracy and precision using tools.; 3E evaluate models according to their limitations in representing biological objects or events; 10C analyze the levels of organization in biological systems and relate the levels to each other and to the whole system
13.1 Ecologists Study Relationships TEKS 2F, 3E, 10C KEY CONCEPT Ecology is the study of the relationships among organisms and their environment.
13.1 Ecologists Study Relationships TEKS 2F, 3E, 10C ! Ecologists study environments at different levels of organization. Ecology is the study of the interactions among living things, and between living things and their surroundings.

13.1 Ecologists Study Relationships TEKS 2F, 3E, 10C ! Ecological research methods include observation, experimentation, and modeling. Observation is the act of carefully watching something over time. Observations of populations can be done by visual surveys. – Direct surveys for easy to spot species employ binoculars or scopes. – Indirect surveys are used for species that are difficult to track and include looking for other signs of their presence.
13.1 Ecologists Study Relationships TEKS 2F, 3E, 10C Experiments are performed in the lab or in the field. – Lab experiments give researchers more control. – Lab experiments are not reflective of the complex interactions in nature. – Field experiments give a more accurate picture of natural interactions. – Field experiments may not help determine actual cause and effect.
13.1 Ecologists Study Relationships TEKS 2F, 3E, 10C Computer and mathematical models can be used to describe and model nature. Modeling allows scientists to learn about organisms or ecosystems in ways that would not be possible in a natural or lab setting. Ecologists use data transmitted by GPS receivers worn by elephants to develop computer models of the animalʼs movements.

Section 13.1 Ecologists Study Relationships KEY CONCEPT . Ecologists study environments at different levels of organization. The biosphere is the sum of all biomes on earth. It includes all living organisms on earth
Ecology is the study of the relationships among organisms and their environment. VOCABULARY ecology ecosystem community biome MAIN IDEA: Ecologists study environments at different levels of organization. Write a description of each level of organization in the table. Also, provide an example for each level. Level Description Example 1. organism .
Ecologists study relationships within each level of organization and also between levels. For example, researchers may study the relationships within . books, and write answers to the questions.

potential problems occurring in the organisms’ environment, and gives ecologists a “heads up” if something is going wrong. But it is not enough to simply know if the number of organisms in an area is going up or going down; ecologists need to know why the number of organisms is fluctuating. So, one of the main questions ecologists

35.1 Behavioral ecologists ask both proximate and ultimate questions Behavioral ecologists study what animals do when interacting with their environment Behavior can be interpreted in terms of proximate causes and ultimate causes with the environment –Proximate causes

It WAS a powerful good adventure, and Tom Sawyer had to work his bullet-wound mighty lively to hold his own against it. Well, by and by Tom's glory got to paling down gradu'ly, on account of other things turning up for the people to talk about--first a horse-race, and on top of that a house afire, and on top of that the circus, and on top of that the eclipse; and that started a revival, same .
