Chapter 2 Principles of Ecology. 2.1 Organisms and Their Relationships. What is ecology?. Oikos Greek for “homestead” Ology means “study of” Scientific study of interactions among organisms and their environment

Endosymbiosis. Evidence of Symbiosis. Both mitochondria and chloroplasts contain DNA, which is fairly different from that of the cell nucleus, and that is similar to that of bacteria (circular and smaller).

Ecology 101. Ecosystems and Symbiosis. Biosphere - The total water, land and atmosphere that can sustain life. Biosphere. Ecosystem – all of the living and non-living parts of an environment. Biosphere. Ecosystem. Community – group of populations in a specific area. Biosphere.

6.1 Relationships in the Ecosystem. Predators and Prey. Predator= A consumer that actively hunts other living organisms. Prey= The organism that a predator eats . Lynx and Snowshoe Hare. Predator and prey population sizes are closely linked.

1.2.3. Characteristics of Life. How do we know if something is alive?. It has organization – cells, tissues, organs, etc. It uses energy Grows and develops Excretes Reproduces Responds to the environment Adapts to the environment. Organisation. Unicellular or multicellular

Globalization – what is it about?. Manfred Steger; Globalization – a very short introduction. Perceptions of the World. Different levels: tribal, local, regional, national, international and global. .

Ecology Quiz Review. Empty slide to keep flashcards in order. What is the study of living things and how they interact with their environment?. ECOLOGY. What is… An organism? A species? A population? A community? An ecosystem? A Biome A Biosphere?. Gets bigger as it goes down.

What do you think of?. Symbiosis, or the living together of different organisms, allows some species to live in otherwise hostile environments, so it can be a powerful mechanism of evolutionary change.

Unit 14 Animals of the Benthic Environment. Benthic organisms. Benthic organisms are those that live in or on the ocean floor More than 98% of known marine species are benthic The vast majority of benthic species live within the shallow continental shelf…Why?.

Small Mammals . By: Grant Hatch. American Porcupine.

Chapter 27: Prokaryotes. The total biomass of the prokaryotes is 10 times greater than that of all the eukaryotes!! Bacteria are UBIQUITOUS due to their adaptability. Huge genetic diversity as demonstrated by sequencing their DNA. Classification.

Phylum Cnidaria. What are Cnidarians?. http://www.youtube.com/watch?v=wOXO4F9dzd8. Groups of Cnidarians. Jellyfishes (class Scyphozoa – cup animals) Hydras (class Hydrozoa)* Sea anemones (class Anthozoa – flower animal)* Corals (class Anthozoa – flower animal)*

Symbiotic Relationships. 8 th Grade Science. Objectives of the Symbiotic Relationships Lesson.

Introduction To Capital Markets - 1. By Prof. Shantanu Gokhale. Investments. Current commitment of money for a period of time - to derive future payments that compensate the investor for The time the funds are committed The expected rate of inflation The uncertainty of the future payments

Symbiosis . Unit 1: Ecology and Sustainability of Ecosystems. Symbiosis. Symbiosis refers to any close relationship between two different species. Each species often develops specialized behaviors, life cycles, or structures . . 1. Mutualism.

Community Ecology. Species Interactions. Remember populations have interacting members a specific species. Communities have interacting members of different species. Think about your neighbor hood. You people, cats, dogs, birds etc. all living in the same community. Predation.

LIVING RELATIONSHIPS. SYMBIOSIS. Other Nutritional Relationships:. SYMBIOSIS - Any close relationship between two organisms of different species. COMMENSALISM. Benefits one organism; the other organism neither benefits nor is harmed This is an example of the cattle egret and a rhinoceros

Biotic factors. Biomass or Biomes Interactions between organisms Productivity In fossil record we recognize: Relationship between organisms Paleoproductivity. Relationship between orgnisms.

Nitrogen Fixation. Our goal is to learn how N 2 an inert gas, becomes part of the structure of organic molecules. Secondly, to study the function of nitrogen compounds in plants and bacteria. To study the nitrogenase complex and learn its secrets for fixing nitrogen. 450 o C.
