(2) biodiversity
There are millions of different types of organisms living on Earth. Biological diversity, also known as biodiversity, refers to the wide variety of living organisms across different habitats like rainforests, ponds, deserts, seas, soil, and polar regions. Each habitat is home to unique species that have adapted characteristics to survive there. Scientists estimate there are 10 to 100 million kinds of organisms on Earth, so they classify organisms into groups based on similarities to study them more effectively.
Ecological niche
Ecological niche refers to an organism's role and position in its environment, including where it finds food and shelter and what environmental conditions it requires. An organism's niche is influenced by biotic factors like availability of food and predators as well as abiotic factors like temperature, soil nutrients, and light levels. Earthworms are an example of niche construction, as they physically and chemically modify soil in a way that allows them to survive on land. Niches can be fundamental, representing all possible resources an organism could use, or realized, reflecting the niche an organism actually occupies due to competition. The competitive exclusion principle states that two species with identical niches cannot coexist long-term. Resource partitioning allows similar species to co
Biology Form 4 Chapter 8 :Dynamic Ecosystem Part 2
This document discusses types of ecological relationships and succession. It describes 4 main types of ecological relationships: symbiosis, saprophytism, prey-predator, and competition. Under symbiosis it defines and provides examples of mutualism, parasitism, and commensalism. It then discusses different examples of mutualistic relationships between species. The document also discusses parasitism, commensalism, competition, and succession - the process by which one community gradually replaces another through changes to the environment.
How competition shapes communities
Competition occurs when multiple species rely on the same limited resources. Warblers avoid competition by specializing on different parts of the same trees. Species can coexist if they divide resources in their realized niches to minimize overlap with their fundamental niches. Predation also reduces competition by controlling populations that could otherwise outcompete other species. Greater biodiversity in ecosystems leads to higher productivity and stability.
Ecology1
The document provides an overview of key concepts in community ecology, including species interactions, trophic levels, food webs, succession, biomes, and factors that limit population growth. It defines important ecological terms and describes various types of species relationships, ecological roles, community changes over time, and Earth's major terrestrial biomes.
Keystone Species
The document discusses keystone species and provides examples. It defines a keystone species as a plant or animal that plays a unique and crucial role in ecosystem function. Without it, the ecosystem would be dramatically different or cease to exist. It gives the example of wolves in Yellowstone, whose reintroduction led to thriving populations of many other species. The concept of keystone species was established in 1969 by Robert Paine through his research on sea stars. Keystone species are often predators that control prey populations, like mountain lions, or herbivores that shape habitats, like elephants in Serengeti. The disappearance of a keystone species can start a domino effect leading to ecosystem failure.
DP Biology Option C.1 Species and Communities
The distribution of species is affected by limiting factors such as temperature, water availability, and soil characteristics. Each species has a range of tolerance for these factors, and is excluded from areas outside this range. Species distributions also depend on the availability of resources like food and breeding sites. Within a community, each species fills a unique ecological niche defined by its habitat and interactions. The competitive exclusion principle states that two species cannot coexist indefinitely if their niches are identical. Species interactions in a community include competition, predation, parasitism, mutualism and commensalism. Keystone species have a disproportionate effect on community structure through their role in the food web.
Option C Ecology and Conservation
All plant species are restricted to certain geographical areas and particular habitats according to certain abiotic conditions

4 Patterns
Communities have patterns of succession, stratification, and zonation over time. Succession involves changes in species composition from colonizers to a climax community. Stratification creates vertical layers from canopy to forest floor. Zonation forms bands of organisms along environmental gradients of factors like temperature, water, and tide.
Chapter 8 dynamic ecosystem Form 4 Biology
This document describes the process of ecological succession in ecosystems. It provides the example of succession in a mangrove swamp ecosystem, where pioneer species like Avicennia help build soil conditions over time through their root systems to allow later successor species like Rhizophora and Bruguiera to colonize. The document also outlines the five stages of succession that occur as a pond gradually shallows over time, from pioneer aquatic plants to eventual colonization by woody plants as the pond transforms into land.
Communities
1) Ecosystems have trophic structures that determine energy flow and nutrient cycling through feeding relationships between species organized into trophic levels.
2) Producers, which include photosynthetic plants, algae, and bacteria, occupy the first trophic level and support all other levels by harnessing solar or chemical energy.
3) Consumers are organisms that feed on producers or other consumers and are ranked according to the trophic level they occupy, such as herbivores on the first level or carnivores on higher levels.
Keystone and Foundation Species 2011
The document discusses the concepts of keystone and foundation species through several examples. It describes research showing that the sea star Pisaster ochraceus is a keystone species that controls populations of mussels, maintaining diversity in intertidal communities. Studies on kangaroo rats and prairie dogs also demonstrate how removing these species can transform ecosystems by reducing diversity. Kelp is provided as an example of a foundation species as a dominant primary producer.
Eog review ecosystems (1)
This document defines key terms related to ecosystems, including biome, biotic and abiotic factors, producers, consumers, decomposers, populations, communities, niches, limiting factors, food chains, food webs, and human impacts such as habitat reduction, pollution, and nutrient cycles. It provides examples of different biomes and describes the roles of different organisms within ecosystems.
Lesson 24 ecological niche
1) An ecological niche refers to the function a species carries out in its habitat through its use of resources and interactions with other community components.
2) If two species occupy the same exact ecological niche, competition will occur until one species dominates.
3) All species that live in the same habitat have some differences in their niches that allow them to avoid competition, even if aspects of their niches overlap.
Ecological niche 811
This document summarizes the concept of ecological niche. It discusses niche as a species' habitat requirements, its functional role in an ecosystem, and its position within a local community. Key concepts covered include the fundamental niche representing all conditions a species can persist in, versus the realized niche reflecting interactions with other species; competitive exclusion and limiting similarity regarding how similar niches can be for coexistence; and modes of coexistence such as niche differentiation and dominance hierarchies.
Community Ecology
Community ecology is the study of interactions among populations that live together in a common environment. Species interact through their ecological niches, which are influenced by competition for resources. These interspecific interactions include competition, predation, parasitism, commensalism, and mutualism. Long-term coevolution occurs between interacting species like predators and prey or parasites and hosts. Predation places selection pressure on both predators and prey and has driven the evolution of anti-predator adaptations in prey species like camouflage and warning coloration. Community structure and diversity change over time through ecological succession as species composition transitions from pioneer to climax communities following disturbances.
Chapters 17 20 ecology
1. The document discusses key concepts in community ecology including species diversity, guilds, food webs, succession, and landscape dynamics.
2. Species diversity is measured by counting species and their relative abundances. A dominant species is most abundant while a keystone species has a large impact relative to its abundance.
3. Landscape features like habitat fragmentation can create patches that impact species diversity depending on patch size and isolation from other habitats.
Community ecology
Community ecology examines the interactions between populations of different species living in the same area. Species compete for limited resources but can coexist through mechanisms like resource partitioning, where species differentiate their use of resources to reduce competition. Disturbances can alter communities, initiating primary or secondary succession as the community reestablishes itself over time. Keystone species play an outsized role in community structure and ecosystem function.
5.1 communities & ecosystems
This document defines key terms in ecology like ecology, ecosystem, population, community, and species. It distinguishes between autotrophs and heterotrophs, and describes the three types of heterotrophs - consumers, detritivores, and saprotrophs. It explains what a food chain and food web are, and how to determine the trophic level of organisms. It also covers energy flow through ecosystems and food chains, and how nutrients must be recycled unlike energy.
Ecology and niche
The document discusses niches and competitive exclusion in ecology. It defines key terms like ecology, habitat, population, niche, and competitive exclusion. It then presents a fictional story where Brother Gregory is investigating which microbe species is competitively excluding the yeast and preventing wine fermentation at a winery. Data on the temperature and pH niches of different microbe species is collected. Based on comparing the yeast's niche to the data, one can determine which microbe species is responsible for the contamination. The document also explains that while niches can overlap, the principle of competitive exclusion states that no two species can occupy exactly the same niche indefinitely.
Dynamic Ecosystem
The document summarizes the abiotic and biotic components of ecosystems. Abiotic components include non-living factors like temperature, light intensity, and soil composition. Biotic components are the living plants and animals that interact with each other and their environment. These interactions include producer-consumer relationships in food chains and webs, as well as symbiotic relationships like mutualism, commensalism, parasitism, and saprophytism. Succession over time transforms environments like mangrove swamps as pioneer species establish and later species move in.
Ecological niche
An ecological niche describes how a species interacts with and fits into its environment, including obtaining resources like food and shelter, and reproducing. A niche encompasses all biotic (living) and abiotic (non-living) factors. The fundamental niche is the full range of environmental conditions a species can tolerate without competition from other species. Species niches depend on factors like temperature, resources, and predators. Niches can overlap if species partition resources in non-competing ways, like dolphins and seals eating different types of fish.
Ecosystems paz de la rosa, 2013-
An ecosystem is comprised of both living and non-living components that interact in the same environment. There are many different types of ecosystems including rainforests, polar regions, mountains, and bodies of water. Within an ecosystem, organisms can be classified as producers that make their own food, consumers that eat other organisms, or decomposers like fungi and bacteria that break down dead remains and nutrients.
Arid Zone Ecology
1) Ecology is defined in multiple ways including the study of interrelationships between organisms and their environment, and the study of the structure and function of nature.
2) Ecology can be divided based on levels of organization such as species, population, community, and ecosystem ecology. It can also be divided based on habitat into areas like hydroecology and terrestrial ecology.
3) Xerophytes are plants that grow in physically or physiologically dry habitats and have adaptations like succulence, reduced leaves, sunken stomata, and extensive roots to cope with drought and salt conditions.
Community ecology...1
Community ecology is the study of the interactions between species within a biological community. A community is defined as an assemblage of plant and animal species that occur together in a specific habitat. Characteristics of a community include species diversity, dominance by one or a few species, trophic structure consisting of producers, consumers, and decomposers, and successional changes over time. Communities can be classified and analyzed based on quantitative characteristics like frequency, density, and cover, and qualitative characteristics like physiognomy, phenology, and stratification. Ecotones form transitional zones between two adjacent communities, and the biological spectrum indicates the distribution of life forms in a community.
IB Biology Ecology Optional Topic C 2015
The document discusses key concepts in ecology including species, communities, ecosystems, trophic levels, and nutrient cycling. Some key points:
- A species is a group of organisms that can potentially interbreed, while a community is formed by populations of different interacting species living together. An ecosystem includes both the living community and the abiotic environment with which it interacts.
- Organisms are classified based on their method of nutrition as either autotrophs (producers) or heterotrophs (consumers, detritivores, saprotrophs). Energy and nutrients flow through ecosystems via trophic levels.
- Carbon and nutrient cycles like nitrogen and phosphorus are essential for continued availability of those elements

Keystone and Foundation Species
This document discusses different examples of keystone and foundation species. It provides Robert Paine's research on the sea star Pisaster ochraceus, which controls populations of mussels and maintains high biodiversity in intertidal zones. It also discusses James Brown's research on kangaroo rats in desert ecosystems and how their removal changed the plant community composition and increased grasslands. Foundation species like kelp are also discussed as dominant primary producers that many other species rely on for food and shelter.
Basics
The document provides an overview of nutrition basics including defining nutrition, reputable nutrition research methods, categorizing nutrient needs, understanding calories and energy nutrients, analyzing the standard American diet, calculating percentages of calories from carbohydrates, fat and protein, functions of vitamins, minerals and water, factors influencing food choices, assessing nutritional status, establishing dietary reference intakes, using food guides to plan meals, and using exchange lists to plan meals.

- Red blood cells (erythrocytes) transport oxygen from the lungs to tissues and carbon dioxide from tissues back to the lungs. They develop from stem cells in the bone marrow in a multi-step process called erythropoiesis.
- Mature red blood cells are biconcave disks that are flexible and can change shape, allowing them to flow through narrow blood vessels. They contain the protein hemoglobin which binds oxygen and gives blood its red color.
- Red blood cells have an average lifespan of 120 days, after which they are broken down and recycled. Around 2.5 million new red blood cells are produced every second to replace those that die off.More Related Content

A pond ecosystem includes all living organisms (biotic factors) like phytoplankton, zooplankton, larger invertebrates, fish, frogs, and turtles interacting with each other and their non-living (abiotic) environment of humus, oxygen, light, heat and minerals. Phytoplankton are primary producers at the bottom of the food chain, while zooplankton and larger invertebrates act as primary and secondary consumers, and vertebrates like fish and frogs are tertiary consumers. Together these biotic and abiotic components make up the balanced aquatic pond ecosystem.
Chapter 4 : Basic cooking principle & food science
Heat causes molecular changes in foods that can alter texture, flavor and appearance. When proteins are heated, they undergo coagulation and denaturation, becoming firmer. Carbohydrates may caramelize or gelatinize with heat. Fats can melt or break down if overheated. Water can evaporate or boil from foods with increasing temperature. Understanding these molecular changes allows cooks to control results.
Food Technology Proteins
Proteins are made up of carbon, hydrogen, oxygen, phosphorus, nitrogen, and sulfur. They function for growth, maintenance, energy, and formation of enzymes and hormones. Good sources include meat, fish, eggs, milk, and cheese. Deficiency can cause stunted growth and kwashiorkor. Proteins are made of amino acid chains. Denaturation and coagulation alter the protein structure. Heat, acid, salt, and enzymes can cause denaturation. The Maillard reaction is non-enzymatic browning during cooking involving amino acids and sugars.

Matter vocabulary
This science document for 4th graders introduces key vocabulary about matter including the three states of matter - solid, liquid, and gas. It discusses the building blocks of matter at the particle level including protons, neutrons, and electrons and how heat and cold can cause matter to change states through processes like melting, freezing, evaporation, and condensation.
Matter workshop
Matter is anything that takes up space and has mass. It is made up of particles and can be found in four states: solid, liquid, gas, and plasma. Matter has shape, volume, and mass. Solids have particles that are tightly packed and do not change shape. Liquids have particles that are loosely packed and can flow and change shape but maintain a constant volume. Gases have particles that are far apart and spread out, changing both shape and volume. Matter can change states when heat or cold is added through processes like melting, freezing, boiling, and condensation.
