Here’s the background information you need to answer this question.

• An ecosystem can stay balanced with minor changes in its living (biotic) and non-living (abiotic) parts.
• Major changes can lead to long-term impacts and loss of biodiversity.
• Changes can occur due to:
• Natural events
• Human activities
• Humans, as a biotic factor, influence important aspects of ecosystems.
• When multiple changes occur at once, it can stress ecosystems.
• Extreme events, such as:
• Long droughts
• Floods
• Changes in species populations can permanently alter ecosystems and their functions.
• The current extinction rate is at least 100-1000 times higher than the normal rate seen in the fossil record, indicating a severe imbalance in ecosystems.
• Technology can help access real-time data to study changes in populations and growth in specific areas.

Here’s the background information you need to answer the next question.

• 🌱 An ecosystem can stay balanced with small changes in its living (biotic) and non-living (abiotic) parts.
• ⚠️ Big changes can lead to long-term effects and loss of biodiversity.
• 🌍 Changes can occur due to:
• 🌪️ Natural events
• 👥 Human activities
• 🧑‍🤝‍🧑 Humans impact important aspects of ecosystems.
• 📉 The current extinction rate is 100-1000 times higher than normal, indicating a serious imbalance in ecosystems.
• 🧑‍🎓 High school students should explore:
• 🔍 Reasons for today’s rising extinction rates
• 📉 Effects of declining biodiversity.
• 💻 Technology can help students access real-time data to study changes in populations in specific areas.

Here’s the background information you need to answer the next question.

• 🌍 The great diversity of organisms and ecological niches results from over 3.8 billion years of evolution.
• 🦠 Populations of individual species and groups of species create a vast reserve of genetic diversity.
• ⚠️ Loss of genetic diversity in a population increases its probability of extinction.

Here’s the background information you need to answer the next question.

• 🌱 Ecosystems change due to natural and human factors.
• 🔄 They experience cycles of ups and downs around a balanced state.
• ⚠️ Human activities can increase the rate of these changes, leading to imbalances that affect how many individuals of different species can live in an area.
• 📊 To study these changes, we use real data to examine:
• 🔄 Matter and energy flow
• 📈 Population dynamics
• ♻️ Nutrient cycles in ecosystems.
• 📝 Tools like graphs, charts, and algebra help explain concepts like:
• 📏 Carrying capacity
• ⚖️ Balance within ecosystems by looking at local or regional population changes.

Here’s the background information you need to answer the next question.

• 🌍 An ecosystem can stay balanced with small changes in its living (biotic) and non-living (abiotic) parts.
• ⚠️ Large changes can lead to long-term effects and loss of biodiversity.
• 🌪️ These changes can occur from:
• 🌿 Natural events
• 🏙️ Human activities
• 👥 Humans, as part of the ecosystem, can affect important factors.
• ☀️ Climate is influenced by feedback loops involving:
• 🌊 Sunlight
• 🌊 The ocean
• 🌫️ The atmosphere
• 🌱 Living things
• 🌡️ Rising global temperatures cause more extreme weather, impacting both living and nonliving factors.
• 🔄 When multiple changes happen at once, it can stress ecosystems.
• 📉 The current extinction rate is 100-1000 times higher than normal, indicating a serious imbalance in ecosystems.
• 💻 Technology can help scientist access real-time data to study changes in populations in specific areas.

First Option: Key – As the waters warm in their current habitat and the likelihood of deep cold-water pools decrease, these species may migrate to the colder waters further north. Second Option: As the water temperatures increase, some marine species will be able to adapt to the changing environment while species that depend on deep cold-water pools will not be able to. Third Option: Key – The warming trend will provide a competitive advantage to organisms that thrive in warmer waters. Fourth Option: Key – Because phytoplankton blooms occur when ice melts, less available ice will result in smaller phytoplankton blooms, which will provide less available energy for the entire food web. Fifth Option: Phytoplankton blooms will not occur in the winter with limited to no sunlight at the high latitudes of the Bering Sea and Arctic Ocean.
