Ecosystems are defined as the interactions between living organisms and their environment. Energy from the sun enters ecosystems through photosynthesis by primary producers like plants. This energy is then transferred between trophic levels as organisms consume one another, though typically less than 10% of the energy is transferred to the next level. Nutrients also cycle through ecosystems, with processes like decomposition and nitrogen fixation carried out by microorganisms returning nutrients to the inorganic environment to be reused. Human activities are now impacting global nutrient cycles through activities like agriculture, fossil fuel use, and deforestation.

BIO Module 6 Overview
Ecosystems and Ecology
This module will continue the examination of fundamental concepts related to ecology. It will introduce the complex phenomena of interactions between organisms and their habitats, as well as the delicate interactions between communities of organisms. It will explain why changing one part of a community can lead to unexpected consequences. This module will also examine the concept of populations and their growth curves. This material is relevant to the question of a population's "carrying capacity," and, in turn, the Malthusian theory of overpopulation. Finally, you will delve into the fascinating issues surrounding instinctive and learned behavior among animals.

9A
Describe the flow of atoms through the carbon, nitrogen, phosphorus, and hydrologic cycles.
9B

9J
Explain why people in poor countries eat mostly plant material.
9K

Defining species
1. What is the definition of species?
2. What is the biological species concept?
3. Understand the term reproductive isolation, and how this happens due to pre zygotic and post zygotic barriers. Study Fig 22. 3 and learn about the different mechanism which do not allow members of different species to interbreed. Study the examples under each category to gain a better understanding.
4. What are the limitations of the biological species concept? For eg, we cannot learn anything about species when studying fossils or asexually reproducing organisms.
5. What are some other definitions of species? Read about the morphological, ecological and phylogenetic species concept and how are they different from the biological species concept?
Concept 22.2 Pg 423-427
Allopatric and sympatric speciation
1. How are species formed? Is geographic separation necessary for the same?
2. Read about allopatric and sympatric speciation and how speciation occurs in both instances. What is the evidence for allopatric speciation? Read about the example of the species of snapping shrimp.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
