Soap is a salt of a carboxylic acid made from reacting natural fats/oils with an alkali like sodium hydroxide or potassium hydroxide. Soap has both a hydrophilic ionic head that is soluble in water and a hydrophobic tail that is soluble in oils/grease. Detergents are similar but are made synthetically from petroleum and have a sulphonate or sulphate group instead of a carboxylate group. Both work by lowering the surface tension of water to emulsify and suspend oils/grease for removal. Detergents are more effective than soap in hard water since they form soluble salts rather than insoluble precipitates.

This document discusses different types of population interactions and life history strategies in organisms. It covers four types of population interactions: 1) Positive interactions like mutualism and commensalism where one or both species benefit. 2) Parasitism where one species (the parasite) benefits at the expense of the other (host). 3) Predation where one free-living species (the predator) benefits by preying on another. 4) Negative interactions like competition and amensalism where at least one species is harmed. It also discusses different life history strategies around breeding and offspring production employed by different organisms.
The document discusses key concepts around niches and interactions between species in an ecosystem. It defines niche as the role and habitat of a species, including biotic and abiotic factors. It explains that species compete for resources if their niches overlap too much. Specialized species have narrow niches and are more vulnerable to extinction from environmental changes. Convergent evolution and coevolution can cause different species to evolve similar traits to fill similar niches or as they interact and exert selection pressures on each other over time.
No, the evolution of thicker fur in rabbits in response to a colder climate is an example of natural selection, not coevolution. Coevolution requires adaptations occurring in two or more species that interact and evolve in response to each other over a long period of time. The rabbits evolving on their own in response to the abiotic environment is a case of natural selection.
Ecological Interactions - Mutualism, Commensalism & NeutralismRahul M. Prathap
Ecological interactions are the effects an organism have on another in an ecosystem. This slide describes Mutualism, Commensalism and Neutralism with examples.
This document defines key terms related to ecology and ecosystems. It explains that an organism is a single living thing, a population is a group of the same organism in an area, and a community is multiple interacting populations in the same place. An ecosystem is defined as a community interacting with both biotic and abiotic elements of their environment. The document also defines habitat, biodiversity, succession, biomes, climate, and provides examples of different land and water biomes.

This document discusses the characteristics of living and non-living things. It explains that living things such as plants, animals and humans all have the life processes of nutrition, interaction, and reproduction. Nutrition involves taking in food, interaction involves relationships and communication, and reproduction involves creating new living things. The document provides examples of how these life processes apply to humans, animals and plants. It also discusses non-living things and gives examples of natural and man-made non-living things.
Chapter 4 interdependence among living organisms and the envirronmentIzudin Hasan
This document discusses interdependence among living organisms and the environment. It covers topics such as species, populations, communities, habitats, ecosystems, interactions between living organisms including predator-prey relationships, symbiosis, competition, food webs, and the importance of photosynthesis. Photosynthesis produces oxygen and food for animals while using carbon dioxide, and the carbon and oxygen cycles help regulate gas levels on Earth. Conservation efforts aim to preserve natural resources for future generations.
Community
all the organisms that live together in a place
Community Ecology
study of interactions among all -populations in a common environment
In what ways do populations interact?
Community – all the organisms that live together in one place
Community ecology – study of interactions among all populations in a common environment.
Interspecific interactions – among individuals of the different species.
Intraspecific interactions – among individuals of the same species.
Species Interaction…
-A traditional approach to population interactions has been to consider the direct pair-wise interactions.
Community Ecology is the study of interactions among all populations in a common environment.
Species Interaction is a traditional approach to population interactions has been to consider the direct pair wise interactions.
Two populations may or may not affect each other; if they do, the influence may be beneficial or adverse
Types of Population Relationships:
Interspecific interactions:
Competition and Coexistence
Predation
Mutualism
Commensalism
Intraspecific Interactions
Grasshoppers provide an animal example. Individual grasshoppers deprive their fellow conspecifics of food (exploitation competition).
It is probably a major factor involved in the evolution of plumage patterns in birds.
during intraspecific competition, animals will use whatever weapons are available to them and this makes it likely that the nature of the weapons determines the nature and location of patterns.
This document summarizes key concepts about ecosystems, including:
1. The roles of producers, consumers, and decomposers in energy flow and nutrient cycles.
2. Examples of food chains and food webs that demonstrate how energy transfers between organisms.
3. The water, carbon, and oxygen cycles and how they circulate important nutrients.
4. Interactions between species like predation, symbiosis, competition and their effects on populations.
5. Factors like disease, weather, food and predators that influence population sizes.
6. Human activities that can disrupt ecosystems and steps to address effects on the environment.
Ecology is the study of interactions between living organisms and their environment. It examines both biotic factors like plants, animals, and microorganisms, as well as abiotic factors such as sunlight, water, and soil. Ecology views environments holistically and studies the complex relationships within and between populations in an ecosystem. Organisms depend on each other through food webs, with plants and algae as primary producers, herbivores and omnivores as primary consumers, and carnivores and decomposers recycling nutrients and matter. Ecology analyzes these interactions across different levels of organization from organisms and populations to communities, ecosystems, and the global biosphere.
This document discusses key concepts in ecology including different levels of ecological organization, abiotic and biotic factors, habitat and niche. It also describes different types of ecological relationships between organisms including mutualism, commensalism, parasitism, and predation. Examples are provided to illustrate each relationship type. The levels of ecological organization include the biosphere, ecosystem, community, population, and organism.
Relationships Among Organisms PPT(1).pptxShenazHakam
This document provides definitions for key vocabulary terms related to relationships among organisms, including predation, competition, mutualism, commensalism, parasitism, interdependence, coevolution, introduced species, and invasive species. It also defines species and ecosystem as prerequisite vocabulary. The document aims to describe the major types of interactions between organisms and explain how symbiotic relationships and invasive species affect the environment.
This document provides information about adaptations and how they help organisms survive in their environments. It discusses three main types of adaptations: structural, behavioral, and physiological. Structural adaptations involve physical parts of an organism's body, like teeth, shells, or camouflage. Behavioral adaptations include activities that help organisms survive, such as finding food, marking territory, and parenting. Physiological adaptations are behaviors controlled by the brain or body tolerances. The document explains how genetic variations within a population can help organisms survive longer through natural selection, as traits better suited for the environment are passed on.
This document discusses habitats and environments. A habitat contains biotic and abiotic factors and provides resources for organisms to survive. Organisms are adapted to their habitat and may have even or uneven distributions. Ecologists study habitats using various sampling methods and measure factors like population sizes and environmental conditions. Feeding relationships between organisms in a habitat are represented by food chains and webs. Population sizes are determined by competition, disease, poisoning, and changes in biotic and abiotic factors.
