Welcome back to the Strategy Course on Study Buddy Shareline. In our first lesson, we explored what strategy really is. Now, let’s clear up one of the biggest confusions people have: the difference between tactics and strategy. At first, they may look similar—but once you understand the difference, you’ll...
Hello and welcome to your very first lesson of the Strategy Course on Study Buddy Shareline. I’m so glad you’re here, because this journey isn’t just about learning some fancy concepts—it’s about learning a skill that can change the way you study, work, and even live your everyday life....
The Power of Self-Compassion: A Podcast Summary Are you kinder to others than you are to yourself? We often forgive our friends’ mistakes and offer them support, but when we make an error, we can be our own harshest critic. This episode of our podcast dives into the important...
Definition of Decomposition Decomposition: The process of breaking down complex organic matter into simpler inorganic substances like carbon dioxide, water, and nutrients. Role of Detritus Detritus: Dead plant remains (e.g., leaves, bark, flowers) and animal remains, including fecal matter, serve as the raw material for decomposition. Steps in the...
Energy Source and Photosynthetically Active Radiation (PAR) The Sun is the primary energy source for all ecosystems (except deep-sea hydrothermal ecosystems). Of the total incident solar radiation, less than 50% is PAR. Plants capture only 2-10% of PAR through photosynthesis, which sustains the entire living world. Energy Flow Characteristics Energy flows in a unidirectional manner:...
Productivity in Ecosystems Definition of Productivity Productivity: Rate of biomass production in an ecosystem, expressed in: Weight: gm⁻² yr⁻¹ Energy: kcal m⁻² yr⁻¹ Productivity helps compare different ecosystems. Types of Productivity Primary Productivity: Biomass or organic matter produced by plants through photosynthesis. Gross Primary Productivity (GPP): Total rate of...
Definition of Ecosystem An ecosystem is a functional unit of nature where living organisms (biotic components) interact among themselves and with their surrounding physical environment (abiotic components). Key Features of Ecosystems Interactions: Organisms interact with each other and with the physical environment. These interactions form cycles, chains, and webs...
Ecosystem – Structure and Function Introduction An ecosystem consists of biotic (living) and abiotic (non-living) components. These components interact, influencing each other and their environment. The flow of energy within an ecosystem integrates these components into a functional unit. Physical Structure of Ecosystems Physical Structure: Formed by interactions between...
Definition & Importance of Predation: Predation is a natural process where one organism (predator) hunts and consumes another (prey). It serves as a means of transferring energy fixed by autotrophic organisms (plants) to higher trophic levels in the food chain. Predation helps regulate the population of prey species, ensuring...
Reproductive Fitness: Populations evolve to maximize their reproductive fitness (also called Darwinian fitness). High reproductive fitness is associated with a high r value (intrinsic rate of natural increase). Reproductive Strategies: Organisms adopt strategies based on the habitat they live in and the selection pressures they face. Two major reproductive...
