Answer:
E) 2
Explanation:
The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.
Answer:
Declining crude birth rates.
Explanation:
Birth rate may be defined as the number of births takes place per year per thousand of the population. The birth rate and death rate may change the population dynamics.
The developing countries shows the expanding population graph as they have more number of people of the reproductive age. The advancement in the medical field results in the decline birth rate that causes the decline of the nature resources.
Thus, the answer is declining crude birth rates.

Answer:
The correct match is given below:
Explanation:
- A flower containing a pistil, stamen, calyx, and corolla – Complete flower. When a flower consists of essential whorls pistil and stamen and accessory whorls calyx and corolla, the flower is said to be complete.
- The collective term for the petals of a flower- Corolla. The corolla is a accessory whorl which consist s of its unit called petal.
- It has pistils, but no stamens - Female flower. A flower with only pistil is called unisexual pistillate flower.
- A stalk which supports the anther – Filament. A typical stamen consists of an anther, connective and a filament.
- A flower that lacks one or more of the following parts: pistil, stamen, calyx, or corolla corolla.—Incomplete flower. A flower which lacks any of the essential or accessory whorl is called incomplete flower.
- A flower that has male parts only – Male flower. A flower with only stamen is called unisexual staminate flower.
- A spore produced by meiosis – Meiospores. Spores can produced by mitosis or meiosis. If it is produced as a result of mitosis it is said to be mitospores.
