Activity 2.3- Biosphere and Interconnections

 Map of Chapter 4 - Energy and Ecosystems: This map shows how energy enters ecosystems, flows through trophic levels, and supports life. It highlights the limits of energy transfer and the role of humans in energy use. 

 

Map of Chapter 7 - Biodiversity: This map explains biodiversity at the species, genetic, and ecosystem levels. It also shows the threats that reduce biodiversity and the strategies for conservation. 

 

Map of Chapter 8 - Biomes and Ecozones: This map presents the variety of terrestrial, aquatic, and human-dominated ecosystems. It emphasizes ecozones, transnational species, and the importance of conservation across borders. 

 

 

Interconnections 

The three concept maps—energy and ecosystems, biodiversity, and biomes—are closely connected because together they explain how life functions and adapts on Earth. Chapter 4 focuses on energy, showing how sunlight enters ecosystems and drives biological processes. Without energy capture by autotrophs through photosynthesis, the rest of the food web could not exist. The laws of energy conservation and efficiency also explain why only limited energy passes between trophic levels, shaping the structure of ecosystems (Freedman, 2018). 

Chapter 7 builds on this foundation by explaining biodiversity. Species richness, genetic variation, and ecosystem diversity all depend on the continuous flow of energy through living systems. For example, diverse ecosystems like tropical forests or coral reefs exist where energy availability is high, supporting a wide range of species. Biodiversity is also essential for resilience, helping ecosystems adapt to challenges such as climate change or human exploitation (Freedman, 2018). 

Chapter 8 then connects biodiversity to place by focusing on biomes and ecozones. These large-scale systems represent how climate, geography, and energy flow shape different ecological communities. For instance, deserts and rainforests contrast sharply in species diversity and productivity because of differences in energy and water availability. Human-dominated ecosystems, such as agroecosystems, show how people directly alter energy flow and biodiversity at global scales. Transnational species, like monarch butterflies, highlight that ecosystems do not follow political borders, making conservation a shared responsibility (Freedman, 2018). 

Altogether, these maps demonstrate that energy is the foundation of ecosystems, biodiversity represents the variety of life within them, and biomes show how these patterns emerge globally. Seeing the interconnections between these concepts helps us recognize the importance of conserving both natural energy flows and the living systems that depend on them.

  What I Most Look Forward to in My Environmental Science Class I look forward to understanding the environmental challenges humanity faces and learning how to address them. I am eager to gain as much knowledge as possible, since I have little background in environmental science, and I believe it is crucial to stay informed and make a positive impact on these issues. What I Think This Class Will Be About I think this class will be about understanding the environmental challenges we face today, learning how to address and prevent these problems, and exploring ways we can improve and protect our environment. I hope to gain knowledge that will help me make informed decisions and take action to have a positive impact on the world around me.

Activity 4.2 Environmental Policy Framework

Davis and Lewicki (2003)   Bryan (2003)   Environmental Framing Consortium (2005)   Identity Frame – How people see themselves and what values shape their decisions. It focuses on personal beliefs and how identity guides environmental actions.   Cultural Context – Traditions, customs, and shared beliefs that influence how communities respond to environmental issues.   Values/Ethics Frame – Moral principles about what is right or wrong in environmental behavior and decision-making.   Fact-Finding Frame – How people use, trust, and sometimes question scientific evidence. It helps identify what counts as credible information.   Technological Context – How innovation and new technology offer solutions or challenges for sustainability.   Scientific Frame – Emphasizes facts, research, and data accuracy to understand environmental realities.   Conflict Management Frame – How groups manage disagreements and find compromise through communicat...

Activity 3.1 – Human Population

  Australia – More Developed Country   Life in Australia is quite comfortable, reflecting a high level of development, with many resources available to people every day .  The birth rate is relatively low , at about 11 per 1,000 people , while the death rate is 7 per 1,000 (PRB, 2024). This results in a slow population growth rate of only 0.4% per year . People live long lives, with men reaching an average of 81 years and women 85 years . Families are small, with women having approximately 1.7 children on average. Additionally, the Gross National Income (GNI) per capita is US$66,260 , showing strong economic stability and access to resources (PRB, 2024). Compared to global averages, Australia has fewer births and higher income, which is typical of more developed countries (Freedman, 2018). You can really see how life, healthcare, and opportunities are very different compared to less developed countries .   Niger – Least Developed Country   Life in Nig...
