The Carbon Cycle01:14

The Carbon Cycle

39.5K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Global Climate Change01:50

Global Climate Change

24.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Positive and Negative Feedback Loops01:18

Positive and Negative Feedback Loops

20.0K
Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires  maintaining an internal dynamic equilibrium:

Effects of feedback01:24

Effects of feedback

694
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

78
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Metabolism of Chemolithotrophs01:15

Metabolism of Chemolithotrophs

144
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

    • Climate Science
    • Ecology

    Background:

    • Global warming is increasing precipitation in tropical regions.
    • Tropical wetlands are sensitive ecosystems that play a role in global biogeochemical cycles.

    Discussion:

    • Increased moisture in tropical wetlands can enhance microbial activity.
    • Enhanced microbial processes can lead to increased emissions of potent greenhouse gases like methane and nitrous oxide.

    Key Insights:

    • Tropical wetlands, increasingly saturated due to global warming, are emerging as significant sources of heat-trapping gases.
    • The changing hydrology of these wetlands is altering their function as carbon sinks or sources.

    Outlook:

    • Further research is needed to quantify greenhouse gas emissions from tropical wetlands under future climate scenarios.
    • Understanding these emissions is crucial for refining climate models and mitigation strategies.
