Pearson 3.1

What is a biome?

A group of ecosystems that share similar climates and typical organisms.

What is an abiotic factor?

Any non living part of the environment.

What is experimentation?

Experiments are made to test hypotheses by gathering data that support or reject he hypothesis.

What is ecology?

The scientific study of interactions among organisms, populations, and communities and their interactions with their environment.

What is an ecosystem?

all the organisms that live in a place, together with their physical environment

What is a biotic Factor?

any living part of the environment with which an organism might interact.

What does the global systems look models middle ring represents?

events, processes, and cycles within the biosphere, atmosphere, geosphere and hydrosphere.

What are he four major global spheres?

The biosphere, atmosphere, hydrosphere and the geosphere

What are the conditions in an environment?

Abiotic and Biotic Factors

What is a community?

An assemblage or different populations that live together in a defined area.

How do you understand global systems?

Developed a model that shows those systems, the processes that operate within each system and ways those processes interact.

What is modeling?

Models help ecologists understand the phenomenon of an excitement. Useful models make productions that lead to the development of additional hypothesis.

What does ecology study?

Natures "houses", organisms that love in those houses, and interactions based on energy and nutrients.

What is observation?

Oftan the first step in the ecological questions. They ask questions that can later lead to the development of scientific hypotheses.

What do excitements in artificial environments show?

They show how plants, bacteria, animals, or artificial communities react to changes such as temperature, lighting, or carbon dioxide concentration.

How are abiotic factors influenced by biotic factors?

When a living thing lives in a abiotic factor or transfers something into the non living partial it could make it both abiotic and biotic.

What is a sustainable human economy?

When they can function without constantly degrading the environment.

What does the global systems models outer ring represent?

a combination of human activities and nonhuman events and processes that can drive changed in Earths global systems.

what is a population?

a group of individuals that belong to the same species and live in the same area.

What is a species?

a group of similar organisms that can breed and produce fertile offspring.

What does the global systems inner circle represent?

contains the kinds of changes in global systems that scientists can measure.

what is causing change in our environment?

human activity

What is the biosphere?

includes all part of earth where life exsists.

What does the biosphere include?

includes everything from bacteria underground to trees in the rainforest. ALL LIVING THINGS

What are the 3 main approaches ecologists rely on?

observation, experimentation and modeling. Many studies involve all 3 approaches with ecologists using tools from DNA analysis to data gathered from satellites.

what do economics do?

they study human "houses" and interactions based on money or trade, energy, and nutrients.
