🐞 Ladybug Ecosystem Simulation - NSI Practice Exam

This project is a Python-based biological simulation developed for the Numérique et Sciences Informatiques (NSI) specialty for the French Baccalaureate. It models the population dynamics of ladybugs and their prey in a closed ecosystem.

Overview

The simulation uses Object-Oriented Programming (OOP) to represent individual ladybugs and their life cycles. It tracks population growth, hunting efficiency, and aging over several simulation days.

Key Features

• Hunting Mechanics: Ladybugs hunt aphids based on food availability. Their nutrition level increases or decreases depending on their success.
• Reproduction System: Female ladybugs can produce descendants (one male, one female) if they reach a specific nutrition threshold.
• Survival & Aging: Each ladybug has a randomized lifespan (200-350 days). The system automatically handles mortality and daily aging.
• Dynamic Ecosystem: Prey population (aphids) follows a 20% natural daily growth rate, balanced by ladybug predation.

Technical Concepts

• OOP (Classes & Methods): Encapsulation of ladybug attributes (sex, age, nutrition).
• Simulation Logic: Implementation of an evolution function to manage daily ecosystem updates.
• Randomization: Use of the random library to simulate biological unpredictability (lifespan, food consumption).
• List Management: Dynamic tracking of populations and new births.
