The correct answer is **b. Limits to reproductive growth**. Logistic growth occurs when a population grows rapidly initially but then slows down as it approaches the carrying capacity of its environment. This is typically due to limits on resources (such as food, space, and shelter) and increased competition as the population size increases, leading to a stabilization of growth as it reaches the limits imposed by environmental factors.

The statement that most accurately reflects the theory of biological evolution through natural selection is: **b. Individuals with certain genetic traits are more likely to survive and reproduce under a specific set of environmental conditions.** This statement captures the essence of natural selection, which involves the differential survival and reproduction of individuals based on genetic variations that confer advantages in a particular

The most accurate statement about a threatened species is: **d. It is likely to become endangered in the near future.** A threatened species is one that is at risk of becoming endangered in the foreseeable future, indicating it is not currently endangered but may soon reach that status if conservation measures are not taken.

The Jacaranda tree that has been deliberately introduced into South African ecosystems is called a **exotic** species. So the correct answer is: a. exotic

b. The precautionary principle The precautionary principle advises taking preventive action in the face of uncertainty, especially in environmental and ecological matters. Given the potential unforeseen consequences of introducing non-native species, applying this principle is advisable to mitigate risks and protect ecosystems.

The correct answer is: b. Background extinction

The correct answer is **c. Functional diversity**. Functional diversity refers to the range of different biological functions or roles that species within an ecosystem perform, which enables interactions between species and contributes to ecosystem resilience and productivity.

d. endemic Biodiversity hotspots are geographical areas that contain high numbers of endemic species, which are species that are not found anywhere else in the world.

Ecological biogeography primarily focuses on: **c. studies the current factors affecting the distribution of plants and animals** While aspects of the other options may relate to broader biogeography or ecological studies, option c most accurately captures the essence of ecological biogeography.

In a food chain, cats and wolves are both carnivorous animals, but they operate at different levels depending on their specific diets and roles in their ecosystems. In this context: - **Cats** (domestic cats) are typically considered secondary consumers as they primarily eat primary consumers (like rodents). - **Wolves** are also secondary consumers, but they can be classified as tertiary consumers in ecosystems where they prey on other

To accurately classify the animals represented in the images, I would need to know which specific animals they are, as the classification depends on their role in the food chain. Here’s a brief explanation for each classification: a. **Primary consumers** - These are typically herbivores that eat producers (plants). b. **Detritivores** - These organisms consume dead organic matter and help in decomposition. c. **Tertiary consumers** -

Without being able to see the image, I can't directly determine which species interaction it represents. However, I can help you identify each type of interaction: a. **Predation**: One species (predator) kills and eats another (prey). b. **Mutualism**: Both species benefit from the interaction. c. **Parasitism**: One species (the parasite) benefits at the expense of the other (the host). d. **Commensalism**: One species benefits while the

I can't view images, so I'm unable to directly identify the species interaction represented in the accompanying image. However, I can help you understand each type of interaction to determine which one aligns with the image you have: a. **Predation**: One species (predator) kills and eats another (prey). b. **Mutualism**: Both species benefit from the interaction. c. **Parasitism**: One species benefits at the expense of the other, often

The correct answer is: **d. in lakes and oceans near the mouths of rivers where large areas are periodically depleted of their normal flora and fauna** Dead zones are areas in aquatic environments where the oxygen levels are very low (hypoxia), often due to nutrient runoff from land, leading to excessive algae growth (eutrophication). When the algae die, their decomposition consumes oxygen, making it difficult for marine life to survive.

I’m sorry, but I can't assist with that.

Energy flow through ecosystems can be illustrated and explained through various frameworks, each highlighting different aspects of how energy is transferred between organisms. Here’s an overview of each option: ### a. Trophic Levels Trophic levels refer to the hierarchical positions in a food chain or food web, specifically how energy flows from one level to the next. 1. **Producers (Autotrophs)**: These are the first trophic level; they

b. organic matter
